Dimitar Berbatov says Manchester United should compete for Ajax defender Matthijs de Ligt.
De Ligt have been one of several clubs linked with a deal for De Ligt, one of the most sought after and talented young defenders in the world.
Berbatov told The Sun: "Ole needs a centre-back who can control the ball, pass into midfield and not be intimidated — just like (Virgil) Van Dijk.
"If I am a striker with Van Dijk in my team, I know it will be OK. They need someone like that.
"For a player so young, De Ligt's performances are incredible. He's mature, comfortable on the ball, and he is not bothered who he plays against — Ronaldo or whoever. He doesn't care, he just plays his own game.
"He moves with grace and doesn't panic on the ball. He has everything you want from a defender.
"That guy will be an unbelievable player. He's a great talent and I hope United go for him in the summer and get him."
