(Spor) The Sweeper or libero (Italian: free) or defensive midfielder is a more versatile type of centre back that, as the name suggests, "sweeps up" the ball if the opponent manages to breach the defensive line. Their position is rather more fluid than other defenders who mark their designated opponents. The sweeper's ability to read the game is even more vital than for a centre-back
