Manchester United find themselves in an unusual position on Sunday. Opposition manager Rene Meulensteen knows more about the United squad than their own manager, David Moyes, having spent 10 years working with the Red Devils.
Meulensteen, who left Manchester last year when Moyes replaced Sir Alex Ferguson, is credited with much of the success United have enjoyed over the past five years. However, his greatest strength as a hands-on coach was his downfall at the club, signalling the end of his time there. Moyes wasn't prepared to offer Meulenteen the same sort of dominant role on the training ground that Ferguson had afforded him.
So, how should Moyes line his team up against a man who knows the players' strengths and weaknesses so well?
