David Luiz says Chelsea must be prepared for a difficult week.

The Blues take on Bournemouth in the EFL Cup quarter-finals on Wednesday before travelling to Leicester City on Saturday.

"It's always a big week," said David Luiz. "We have another competition on Wednesday and then we play Leicester so we have to take it step by step, it's going to be difficult.

"The Bournemouth game is important, it's another competition and another trophy so we're going to try to win it.

"It's going to be difficult, we have to understand that because it's never easy to play in England and play in these competitions so we have to prepare well, rest well and try to win. If we do that then we can enjoy Christmas."
