The Premier League spent a record-breaking £670 million this summer, over £300 million more than the total of any other league in the world and almost as much as La Liga and Serie A combined.
There was a massive influx of talent into the Premier League this transfer window and below, we'll take a look at each Premier League club's best summer signing.
Arsenal: Mesut Ozil
Arsene Wenger drove Arsenal fans nuts this summer after divulging the details of a sizable transfer kitty, but it took until deadline day until Le Professeur actually spent money on a player — he signed Yaya Sanogo and Mathieu Flamini on free transfers earlier in the window.
When the French tactician decided to finally break the bank, he smashed the club record in dramatic fashion, completing a £44 million move for 24-year-old Real Madrid midfielder Mesut Ozil. Whenever you're able to add a top three player at his position you're doing something right.
It took a while, but the 2013-14 Premier League's most expensive summer signing has all the makings of its best.
Aston Villa: Jores Okore
Villa allowed the third most goals in the league last season and it would have been many more had it not been for Brad Guzan. Adding another centre-back was of the utmost importance and Paul Lambert completed a very shrewd deal for Danish international Jores Okore.
Okore, 21, has immense strength and is unafraid of putting in a crunching tackle. His pace also makes him a major asset as it allows him to compensate for the attacking forays of Matthew Lowton and Antonio Luna.
Cardiff City: Gary Medel
Medel is a madman. The 26-year-old Chilean international is reminiscent of Gennaro Gattuso as both are hard-nosed, no-nonsense midfield destroyers.
Cardiff did pay a steep price, over £11 million, but Medel's presence will strike fear into the hearts of opposing players. His nickname, El Pitbull, is a perfect description for his no holds barred style of play.
Chelsea: Samuel Eto'o
We could've gone in a number of directions here as Andre Schurrle and Marko van Ginkel are both great additions, but Chelsea's biggest weakness last season was at centre-forward. The much-maligned Fernando Torres, though he was quite prolific in Europe, was ineffective in league play and the other striker on the books, Demba Ba, scored just two goals in 14 Premier League fixtures.
The 32-year-old Cameroon international will add loads of quality to the Blues' attack and what's more, he was signed on a free transfer. He may not have the blistering pace he had during his time with Barcelona, but the former Anzhi striker will give Jose Mourinho a reliable striker to call upon, and one who's capable of capitalizing on the fantastic service he'll receive from Juan Mata and Eden Hazard, amongst others.
Crystal Palace: Marouane Chamakh
The 29-year-old striker was wasting away at Arsenal and Palace were able to sign him for just over £1 million. In 2010-11, the only season he managed more than 20 appearances for Arsenal, Chamakh scored 11 goals and provided 8 assists in 44 matches.
Those aren't outstanding numbers, but considering he'll be one of the focal points of the Crystal Palace attack, he should certainly be able to replicate that goal-scoring output. The Moroccan international is very good in the air and his hold up play will pay dividends for his 23-year-old forward partner and fellow summer signing Dwight Gayle.
Everton: James McCarthy
The Toffees completed three impressive loan moves for Barcelona starlet Gerard Deulofeu, Manchester City veteran Gareth Barry and Chelsea wunderkind Romelu Lukaku, but it's the permanent signing of Wigan midfielder James McCarthy that could have the biggest impact.
Formerly an Arsenal target, McCarthy is an all-action player who Roberto Martinez was keen on linking up with again, after coaching him at Wigan. Everton could have overpaid for the player as £13 million is a little much for a player on a Championship side, but the 22-year-old Republic of Ireland international looks like a star in the making.
Fulham: Fernando Amorebieta
The Venezuelan centre-back joined on a free transfer from Athletic Bilbao and will go a long way in strengthening a rather porous Fulham defense. He's quite slow, but at 6'4" (1.92 m) he has immense strength and is an aggressive tackler.
Alongside the 6'6" (1.99 m) Brede Hangeland, Martin Jol's centre-back pairing should be indomitable in the air and Amorebieta's arrival will give Fulham's set-piece takers another massive target to aim at.
Hull City: Tom Huddlestone
The 26-year-old English midfielder found himself behind Paulinho, Mousa Dembele, Sandro and Etienne Capoue on the depth chart at Tottenham and joined Steve Bruce's Hull City for £5.1 million. He'll bring with him some much-needed Premier League experience and a thunderous right-foot to the KC Stadium outfit.
Liverpool: Simon Mignolet
Mignolet edges out Mamadou Sakho and Iago Aspas because he's begun his Liverpool career in great fashion, enjoying solid performances in the opening three matches of the 2013-14 season. Pepe Reina made a number of errors that eventuated in goals last season, and the Belgian international should put an end to those goalkeeping gaffes.
Though Pepe Reina was sent to Napoli on loan, don't expect for the Spanish international to reclaim his starting role when he returns as Mignolet is one of the finest keepers in the Premier League.
Manchester City: Jesus Navas
City made four big money moves this summer, acquiring Navas, Stevan Jovetic, Alvaro Negredo and Fernandinho. Though Fernandinho will form a devastating midfield partnership with Yaya Toure, Jovetic's versatility will bolster the City front line and Negredo is a reliable goal-getter, it's Jesus Navas that gives City just what they needed: width.
The Sky Blues played too narrowly last season and Navas, who makes a living off getting to the by-line and whipping in crosses, will remedy this issue. Another caveat to the Navas deal is that his presence will allow Pablo Zabaleta, a member of the 2012-13 PFA Team of the Year, to focus on defending as the Argentinian international isn't nearly as good going forward.
Also, keep your eye on Martin Demichelis. The former Bayern Munich man was brilliant at Malaga last season and could have been a major cog in Diego Simeone's superb Atletico Madrid defense, before his move to City. Manuel Pellegrini's side looked poor defensively against Cardiff and Demichelis will go a long way in shoring up a back-line that's currently without its leader, Vincent Kompany.
Manchester United: Marouane Fellaini
David Moyes left it very late, but in the end, he managed to sign a quality player to partner with Michael Carrick. Carrick was fantastic last season and it became abundantly clear that he needed a new midfield mate, given that Ryan Giggs is too old, Anderson has disappointed throughout his United Career, Phil Jones is better as a centre-back, Darren Fletcher is always hurt and Tom Cleverley would be better in an advanced position.
Fellaini is a unique player because his massive stature allows him to bully opposing players off the ball and makes him a menace in the air. Moyes experimented with the Belgian international, playing him as a No. 10 last season, but with Wayne Rooney and Shinji Kagawa already on the books, expect the former Everton man to revert back to his natural role, holding midfield.
Newcastle United: Loic Remy
Remy is the only new player Newcastle brought in this summer, so he's the de-facto winner. The French striker was signed on loan for just over £2 million and will provide a quality alternative to Papiss Cisse, who has been relied on quite heavily since the departure of Demba Ba.
Remy rose to stardom with Marseille and the 26-year-old showed that he could be effective in the Premier League, scoring six goals in 14 appearances in a short stint with QPR. Remy can be used on the flanks, as well as through the middle, and a front three of him, Hatem Ben Arfa and Papiss Cisse should certainly help Alan Pardew's side improve upon their 16th place finish.
Norwich City: Leroy Fer
Gary Hooper and Ricky van Wolfswinkel were crucial additions following Grant Holt's departure, but it was the Canaries' signing of Dutch international Leroy Fer that was their best summer move. Norwich paid only £4.8 million for a player that was worth closer to double that and the 23-year-old will go a long way in strengthening the heart of Chris Hughton's midfield.
He's an all-around talent with sound passing acumen that makes surging runs from his midfield position to help support the attack. Fer has a fantastic work-rate that allows him to cover a ton of ground and that stamina is especially helpful on the defensive side of the ball, where he tracks opposing players, harrying them into losing the ball.
For the price, this deal has the potential to be the signing of the season.
Southampton: Pablo Osvaldo
Victor Wanyama was a great addition, but considering James Ward-Prowse and Jack Cork were already capable of partnering the superb Morgan Schneiderlin, Osvaldo will effect the biggest change.
The former Roma man is an enigma. He's a fiery player and his temperament can sometimes get the best of him, causing him to make rash challenges and pick up otherwise avoidable bookings. It'll be interesting to see how Mauricio Pochettino uses him and Ricky Lambert, because if the two front men are able to carve out a good partnership, Southampton will be full of goals.
He did cost a significant amount, about £13.3 million, but, on his day, Osvaldo is prolific and has all the tools to be a 20-goal scorer in the Premier League.
Stoke City: Marko Arnautovic
Marko Arnautovic is a tremendously gifted footballer who represents a bargain of the highest order after being signed for just £2.6 million. He struggled to make his mark under Jose Mourinho at Inter, but after joining Werder Bremen in 2010, his progress has been remarkable.
He's a physical specimen who will be able to inject a great deal of attacking flair and quality into a Stoke City offense that Mark Hughes has been trying to reinvent. He's more talented than Kenwyne Jones, Peter Crouch and Jonathan Walters, but the versatile forward will probably be used on the wing.
If he's able to continue his 2012-13 form, Arnautovic will revolutionize the Potters' attack.
Sunderland: Jozy Altidore
Paolo Di Canio's side were one of the most active clubs this summer and while Emanuele Giaccherini was a great signing, Altidore will bolster a forward line that managed just 41 goals last season, good for third worst in the Premier League. Steven Fletcher's ankle injury was devastating as the Black Cats didn't really have anyone capable of filling the Scottish international's void.
Altidore was fantastic for AZ last season, scoring 31 goals in 41 matches, and will form a formidable centre-forward contingent with the aforementioned Fletcher. He's been in torrid form for his country as well, and if the American international receives consistent service, he'll show the Premier League that he's drastically improved from that disappointing loan spell with Hull City back in 2009.
Swansea City: Wilfried Bony
Jose Cañas was a great signing, but it's Michael Laudrup's deal for Ivorian striker Wilfried Bony that was the Swans' best summer transfer. Bony, 24, dominated the Eredivisie last season, scoring 31 goals in 30 league matches and his addition will allow for Michu to occupy his preferred position, a withdrawn role behind the centre-forward.
Bony is extremely strong and skilled in the air, and should therefore have no trouble dealing with the more corporeal style of play in the Premier League. When Bony and Michu become effective in link-up play, Swansea will have two go-to scoring options, and that will be a huge boost for the Welsh side that perhaps relied a little too heavily on Michu last season.
Tottenham: Christian Eriksen
So many options here. Paulinho was exceptional for Brazil during the Confederations Cup, Soldado is a world-class goal-poacher who projects to be a prolific scorer in England and Erik Lamela has the potential to become one of the world's foremost stars.
In terms of a signing though, none ranks better than the move for Ajax's Christian Eriksen. The Danish international, like Lamela, has world-class potential and already has a wealth of first-team experience under his belt, despite being just 21 years old. His performance against Manchester City in the Champions League last season shows those who may complain about the lack of competition in the Eredivisie that he's capable of cutting it on the highest level.
Because of his contract situation, Eriksen was available for less than £12 million, and that's a bargain for the player he is now, let alone the player he can become.
West Brom: Stephane Sessegnon
Sessegnon was great for Sunderland during his three-year tenure and Steve Bruce is getting a really quality player. He's incredibly versatile and can be effective in every advanced midfield role, using his agility, dribbling and shooting ability to wreak havoc on opposing defenses.
West Brom has used a 4-4-2 throughout the early part of this season, but a switch to more of a 4-4-1-1 in order to include Sessegnon, instead of either Shane Long or Nicolas Anelka, should surely help a side that has won just one point from their opening three matches.
West Ham: Stewart Downing
Downing was horrible in 2011-12, his first season with Liverpool, managing no goals and no assists in 36 appearances. He was considerably better last season, scoring three goals and providing five assists in 29 league matches, though with all the additions at the forward positions that Brendan Rodgers made, Downing found himself in a precarious position.
Joining West Ham for just over £5 million, about a quarter of the fee Liverpool paid for him two seasons earlier, means the London club will be getting a quality player at a very reasonable price. Downing will receive much more playing time at Upton Park and will provide a boost to the Hammers' mediocre offense.
