Clarence Clyde Seedorf is a Dutch professional football manager and former player. He is regarded by many as one of the greatest midfielders of all time.

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.
