He is the joint most successful Irish footballer of all time, having won 19 major trophies in his club career, 17 of which came during his time at English club Manchester United.

In the sport of association football, a midfielder is an outfield position which plays primarily in the middle of the pitch. Midfielders may play an exclusively defensive role, breaking up attacks, and are in that case known as defensive midfielders. As central midfielders often go across boundaries, with mobility and passing ability, they are often referred to as deep-lying midfielders, play-makers, box-to-box midfielders, or holding midfielders. There are also attacking midfielders with limited defensive assignments.
