Former Chelsea coach Ray Wilkins has big concerns over new signing David Luiz.

The former England midfielder can't understand why the maverick Brazilian has been re-signed for £34million from Paris St Germain.

Wilkins told The Sun: “We are coming up to Christmas and he loves giving presents away. He is a penalty just waiting to happen, especially as a central defender.

“Don't get me wrong, he is a very talented footballer but he is not a centre half as far as I'm concerned.

“He is a holding midfield player or a midfield player. He just makes very, very rash decisions and poor decisions as a centre-half. I don't understand why they brought him back into the fold."
