5: Ron Vlaar
Old Concrete Ron would have been an extremely unlikely candidate to make a move to a top four club this time last year, but as is so often the case a good World Cup has transformed his fortunes.
The Aston Villa skipper is strong in the tackle and as aerially dominant as they come, promising mettle and Premier League experience. When the ball is at his feet he's not as adept as Arsene Wenger might like, but there's no questioning that he would be at the very least a strong backup.
Both Manchester United and Arsenal are said to be keeping their eyes peeled incase Vlaar turns down the new contract Villa are said to be tempting him with.
