Chelsea defender David Luiz admits they weren't at their best for Sunday's 0-0 draw with West Ham.

Luiz admits there was a disappointment in the away locker room.

"Of course we are disappointed," said Luiz. "We didn't play a fantastic game, we didn't create a lot. It was too slow, moving the ball to create the gaps or our movements without the ball, and that is why we couldn't score.

"I think our plan is fantastic,' he confirmed. 'On Sunday we didn't play at our high level so that is why we didn't win.

"We know that many teams now are going to play against us this way, with a low block and trying to play on the counter-attack, so there was not a lot of space but it is up to us to try to find a solution."
