Even though he has not played very much for Manchester United this season, England coach Sven Goran Eriksson still sees Nicky Butt as a key player.
He sits at the back of England's diamond formation and his job is to make lots of tackles and interceptions to stop the opposition making chances.
Like all the Manchester United players he has massive international and European experience and although he's not always very noticeable, his role is very important.
