AC Milan took David Beckham on loan from Los Angeles Galaxy in early-January, and the England midfielder has already impressed for i Rossoneri. Likewise, Real Madrid wasted little time in making their moves, parting with sizeable fees to take Lassana Diarra and Klaas-Jan Huntelaar to the Bernabeu.

The majority of the deadline-day headlines were stolen by English Premier League clubs, with Tottenham Hotspur re-signing Robbie Keane from Liverpool, Charles N'Zogbia leaving Newcastle United for Wigan Athletic, Inter Milan players Olivier Dacourt and Ricardo Quaresma joining Fulham and Chelsea respectively, both on loan, and Jo heading from Manchester City to Everton until the end of the season.
