Arsenal and Manchester United left it late to complete two of the biggest deals of the transfer window as the Premier League's 20 clubs spent over £600million.
West Bromwich Albion and Crystal Palace were the busiest clubs on deadline day after adding four players to their squads, Liverpool and Everton made three signings, while there were some eye-catching loan deals in the Championship.
After just two free transfer signings before the last day of the window, Arsenal went out and smashed their transfer record in the hours before it closed to sign Mesut Ozil from Real Madrid.
The Gunners paid in excess of £40million for the Germany international after signing goalkeeper Emiliano Viviano on loan from Palermo earlier in the day.
Ozil said: "I am thrilled to be joining a club of the stature of Arsenal and am looking forward to playing in the Premier League. From our negotiations it is clear the club has huge ambition and I look forward to being part of an exciting future."
Premier League champions United also finally made a major signing as David Moyes returned to former club Everton to add midfielder Marouane Fellaini to his squad for £27.5million.
United had also been trying to agree a deal for Athletic Bilbao midfielder Ander Herrera, but that failed amid much confusion, and a suggestion of farce.
As expected, Liverpool finalised a triple deal by bringing in Chelsea winger Victor Moses on loan, and defenders Mamadou Sakho and Tiago Ilori on permanent deals from Paris St Germain and Sporting Lisbon respectively.
Moses said: "The target is to get into the top four and for the club to compete in the Champions League - and I'm delighted to be here."
And Sakho said: "I came here because the project that is in place at Liverpool interests me. I'm really looking forward to playing my first game. I know the Liverpool fans are fantastic and while I was in France, it was clear for me to see they are amongst the best in England."
Liverpool's local rivals Everton also added three players to their squad, including the eye-catching capture of striker Romelu Lukaku on loan from Chelsea.
Experienced midfielder Gareth Barry arrived on a season-long loan from Manchester City and the sale of Fellaini allowed Roberto Martinez to raid his old club Wigan Athletic again to nab midfielder James McCarthy for £13million.
Everton also sold Victor Anichebe to West Brom in a deal which could rise to £6million and the striker was one of four new arrivals at The Hawthorns.
Anichebe's signing came on the back of West Brom announcing a club record deal for Stephane Sessegnon of Sunderland, while Morgan Amalfitano joined on loan from Marseille and goalkeeper Lee Camp signed a short-term deal.
Baggies head coach Steve Clarke said of Amalfitano: "He is predominantly a right-sided midfielder who can also operate in a number of other midfield and attacking positions. Morgan is a technical player with good quality on the ball. He also has fantastic work-rate and we believe his game is well suited to the Barclays Premier League."
Sunderland, in addition to selling Sessegnon, completed a double Italian deal after signing striker Fabio Borini on loan from Liverpool and bringing in left-sided player Andrea Dossena from Napoli.
Palace rounded off their summer transfer window with four more signings to take their tally to 15 since winning promotion from the Championship.
Right-back Jack Huntcompleted his move from Huddersfield, Reading defender Adrian Mariappasecured a return to the Premier League, Cameron Jerome was a last-gasp loan addition from Stoke and midfielder Barry Bannan clinched a reunion with Ian Holloway after moving from Aston Villa.
Bannan told Sky Sports: "I played a lot of games last season but the gaffer at Villa has obviously decided to go another way. You can't complain - some managers like you, some don't."
Swansea City took their summer recruitment drive into double figures by signing Getafe striker Alvaro Vazquez on a season-long loan.
"Vasquez is a young player I know from his time at Espanyol and now Getafe," said Swansea boss Michael Laudrup. "He is a little different to the strikers we have and has the characteristics we have been looking for. He will give us a different option."
Aston Villa had done the bulk of their business early in the transfer window, but squeezed in a seventh signing before the deadline as Czech Republic striker Libor Kozak joined on a four-year contract from Lazio.
Villa boss Paul Lambert said: "We've been on this one for the last few months, trying to bring him to the club, so I'm delighted to get it across the line. Libor has an unbelievable scoring record in the Europa League, incredible really."
Of Ireland, chief executive Tony Scholes said: "Arguably the most successful period of Stephen's career to date was when he played for Mark at Manchester City and we hope that he can rediscover that form."
Hull City were unable to finalise the club record signing of West Brom striker Shane Long, but did bring Gedo back on a season-long loan, while Fulham brought in Montenegro international right-back Elsad Zverotic.
Peter Odemwingie was one of the stories of the last transfer window and this time he appeared to secure a move after confirming he is joining Cardiff City from West Brom.
Championship promotion favourites Queens Park Rangers strengthened their squad further by signing Benoit Assou-Ekotto and Tom Carroll on loan from Tottenham, in addition to Harry Redknapp signing Niko Kranjcar for a third time.
Middlesbrough landed a couple of permanent deals just before the deadline as Sierra Leone striker Kei Kamara joined from Sporting Kansas and midfielder Jacob Butterfield arrived from Middlesbrough.
In League Two, Plymouth Argyle secured deals for Hamza Bencherif on a free transfer and Jamie Reckord on loan from Wolves.On the continent, Real Madrid unveiled Gareth Bale after his world-record move from Tottenham Hotspur was officially announced on Sunday night.
Bale's arrival at the Santiago Bernabeu helped to pave the way for Kaka to secure an emotional return to AC Milan.
There was a double deal for Real's city rivals Atletico, who signed defender Toby Alderweireld from Ajax and midfielder Josuha Guilavogui from St Etienne.
