A midfielder is an association football position. Midfielders are generally positioned on the field between their team's defenders and forwards. Some midfielders play a strictly-defined defensive role, breaking up attacks, and are otherwise known as defensive midfielders. Others blur the boundaries, being more mobile and efficient in passing: they are commonly referred to as deep-lying midfielders, play-makers, box-to-box, or holding midfielders. The number of midfielders on a team and their assigned roles depends on the team's formation; the collective group of these players on the field is sometimes referred to as the midfield.
Most managers assign at least one midfielder to disrupt the opposing team's attacks, while others may be tasked with creating goals, or have equal responsibilities between attack and defence. Midfielders are the players who typically travel the greatest distance during a match. Midfielders arguably have the most possession during a game, and thus they are among the fittest players on the pitch.
