A defensive midfielder (holding midfielder or midfield anchor) is a central midfielder who is stationed in front of the defenders to provide more defensive protection, thus "holding back" when the rest of the midfield supports the attack. The defensive midfielder screens the defence by harrying and tackling the opposition teams' attackers and defenders. They also help tactically, for instance, by directing opposing attacking players out to the wing where they have more limited influence, and by covering the positions of full-backs, other midfielders and even the centre-backs if they charge up to support the attack.
