Arsenal rounded off a busy transfer deadline day with the sensational last-gasp £10m swoop for Everton playmaker Mikel Arteta.
The Gunners looked to have missed out on the 29-year-old after Everton rejected a bid for their star midfielder earlier on Wednesday evening.
However, Arteta reportedly forced the issue and Arsenal looked to have reached an agreement with their Barclays Premier League rivals before the 11pm deadline and penned a four-year contract at the Emirates Stadium.
The Spaniard will be joined in north London by three other deadline-day signings, including Brazil left-back Andre Santos from Fenerbahce and Werder Bremen centre-back Per Mertesacker. Israel international Yossi Benayoun has also moved to the Gunners on a season-long loan from Chelsea, who secured a late signing themselves.
While moves for Porto’s Alvaro Pereira and Tottenham’s Luka Modric did not come to fruition, Andre Villas-Boas managed to secure a late deal for Liverpool midfielder Raul Meireles.
In an eerie echo of Fernando Torres’ £50m January switch, the Blues left it until just before the deadline to complete a deal for the Portugal international.
Like Torres, the midfielder submitted a written transfer request, with Liverpool agreeing a fee with Chelsea reportedly in the region of £12m.
Several players left Stamford Bridge yesterday, with Gael Kakuta and Patrick van Aanholt joining Bolton and Wigan on season-long loans, while new signing Ulises Davila penned a similar deal with Vitesse Arnhem.
Stoke smashed their transfer record to sign England striker Peter Crouch from Tottenham in a deal which could ultimately be worth £12m.
Potters boss Tony Pulis had a busy final day of the transfer window, also signing Wilson Palacios from Spurs and striker Cameron Jerome from Birmingham.
Recently-promoted QPR continued their spending spree since the recent takeover by Tony Fernandes.
Shaun Wright-Phillips joined from Manchester City and a deal was secured for Sunderland defender Anton Ferdinand, although the club has yet to confirm whether a loan deal for Southampton winger Jason Puncheon was completed in time.
Fellow west London outfit Fulham brought in three signings themselves on deadline day.
Juventus defender Zdenek Grygera penned a one-year in the afternoon, before completing moves for former Porto striker Orlando Sa and highly-rated FC Twente attacker Bryan Ruiz.
Another out-of-favour attacker on the move was Craig Bellamy, who completed a shock return to Liverpool on a two-year deal from Manchester City.
Joe Cole left Anfield to join French champions Lille on loan, while Denmark international Christian Poulsen also moved to France to join Evian.
David Ngog also left Liverpool to join Bolton, penning a three-year deal at the Reebok Stadium.

Royston Drenthe was drafted in from Real Madrid for the season, while Denis Stracqualursi joined from Argentinian side Tigre.
Manchester City completed the shock signing of Owen Hargreaves on a one-year deal following his release by cross-city rivals United.
Tottenham were thwarted in their attempts to sign Bolton defender Gary Cahill, but managed to bring in Scott Parker from West Ham.
As well as Crouch, Spurs also saw Alan Hutton depart as he penned a deal until 2015 with Aston Villa. They also allowed Jermaine Jenas to join Villa on a season-long loan, while David Bentley signed a loan deal with West Ham.
Blackburn completed the signing of Birmingham defender Scott Dann, while Shaun Maloney joined Lancashire rivals Wigan from Celtic.
Recently-promoted Swansea made three signings, bringing in Daniel Situ from Lens and free agents Gerhard Tremmel and Federico Bessone.
