Sergio Busquets Burgos is a Spanish professional footballer who plays as a defensive midfielder for Major League Soccer club Inter Miami. A deep-lying playmaker capable of directing gameplay through short and calm passes and his singular reading of the game, he is considered one of the greatest defensive 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.
