Crystal Palace finally announced the signing of Algeria midfielder Adlene Guedioura from Nottingham Forest on Tuesday.
The £2.5 million switch was allowed to be completed 12 hours after the 11pm deadline on Monday evening because part of the paperwork on the transfer had already been completed after he made a late dash to South London.
He follows striker Cameron Jerome -- who joined on loan from Stoke -- plus defender Adrian Mariappa and midfielder Barry Bannan in agreeing to move to Selhurst Park on the final day of the window.
He becomes Palace’s 15th signing this summer as Ian Holloway tries to build a side capable of keeping the Eagles in the Premier League and has signed a three-year contract.
The deal was controversial, however, and not just for the delay in its completion, with a number of Forest supporters venting their anger at owner Fawaz Al Hasawi and manager Billy Davies for sanctioning the sale of the 27-year-old.
The Championship club began deadline day hoping to finalise the arrival of three signings, but ended the day empty handed after failed attempts to sign Middlesbrough’s Grant Leadbitter, Wolves’ Bakary Sako and Brighton’s Liam Bridcutt, as well as making enquiries for Hull City's Matty Fryatt.
After the deadline had passed on Monday night there were conflicting reports over whether the deal had been completed and on Tuesday morning the Forest press office were briefing reporters that Guedioura was "still a Forest player".
By lunchtime that had changed, with Forest losing one of their most influential players; the club insisted they were left with little choice because of Guedioura's determination to force through a return to the Premier League.
A statement on the club's official website on Tuesday read: "Despite discussions with Forest chairman and owner Fawaz Al Hasawi, the midfielder was reluctant to stay with The Reds and handed in a transfer request late last night.
"The club would like to thank Guedioura for his contribution during his time at Forest and wish him all the best in the future."
Forest have made a £1.5 million profit on the midfielder, who joined Forest from Wolves in January 2012, first on loan, before becoming a permanent signing for £1 million later that summer.
Wolves retain a 10% sell-on clause for the player they signed from Belgian side Charleroi.
