Chelsea defender David Luiz admits their Europa League final against Petr Cech's Arsenal cannot be about sentiment.

The goalkeeper was part of that cup-winning team in Amsterdam in 2013 and was a mainstay of the Chelsea side during Luiz's first four years at the club.

But the Arsenal keeper will now line up against his former employers in what will be his final game before he retires from football this summer.

"We know already it's going to be difficult to score some goals," Luiz said about the prospect of facing Cech. "He's a great player and the best goalkeeper I ever played with.

"We are great friends and he's a great character but I hope he can be not at the top that day because it's going to help us."
