Paris Saint-Germain defender David Luiz has revealed he is preparing himself for "war" in the club's Champions League last-16 second-leg clash against Chelsea. The 28-year-old star left Chelsea in 2014 to join the Parisians and has revealed his is anticipating a feisty encounter against Guus Hiddink's revitalised team.

In particular, the Brazilian – who won an FA Cup, a Champions League and a Europa League during his time at Chelsea – revealed he is looking forward to facing the combative Diego Costa.

"I'm ready for war, for the battle. I think things are looking good for us to qualify," Luiz said, according to the Daily Mail. "I love giving everything for my team. I know very well it's not easy to play at Chelsea. They know how to get results. We have to be careful."

The former Chelsea man admitted he needs to be cautious of Costa because of his abrasive style, which can cause defenders to lose their cool. "Diego is a great player and his style of play is to play with contact, to speak, to intimidate," he said of Chelsea's controversial striker.

"He tries to get defenders yellow cards. For all the match, he is bang, bang, bang. He can hit you on the head during the match and then after the match come and embrace you."

The Parisians travel to London for the second leg in the round of 16 with a 2-1 advantage over Chelsea.
