Why oh why did they not sign Kevin Strootman last year? A young midfielder who would have improved the team, he cost Roma just €17 million and United will probably have to pay twice that amount next year. Louis van Gaal has not hidden his admiration for a player he values so intensely he altered Holland's formation to 3-5-2 after injury deprived them of Strootman at the World Cup.
Strootman, 24, is not expected to be ready for first-team football until next month, as Roma attempt to go one better and win just their fourth Serie A title.
Harry Redknapp made the second Most Harry Redknapp Signing on deadline day when he brought Niko Kranjčar back to QPR, but he could still make the Most Harry Redknapp Signing in January. Yes, it's Jermain Defoe.
Liverpool are close to finalising a deal for free agent Victor Valdés, who, like Strootman, is recovering from a knee injury.
