Luiz played the position on Sunday as Chelsea beat Aston Villa 8-0 and sparkled there.

"He has the ability to play either position and he's been a fantastic central defender," Lampard told the club's website (www.chelseafc.com).

"People say that central midfield is also a role for him and I think they are right. You still have to have discipline and be in the right position, and you can't take liberties, and against Villa he showed he has the discipline and the ability to do that role."
