Chelsea boss Rafa Benitez is wary of overplaying Juan Mata.

Mata is the team's top appearance maker and topscorer this season.

"We have to be careful if players are playing too many games and if they seem tired, so we check with them and we talk with them," said Benitez.

"The main thing is if you see Juan Mata on the pitch and he is doing well he can carry on, but if we can protect him we will try to protect him. At the moment he is fine."
