Petr Cech believes scoring early will be key to Chelsea turning around their poor home form.

"It is disappointing because we have already had two chances to go top," said Cech. "We are not able to win at home at the moment. We will try to work it out and now the important Christmas period is coming. We know we have two home games and I hope we are going to get it right.

"It's hard to explain because you can see the effort and the way we trying to break the opponents down. The early goal is key. We have been doing that away from home and that has made the games slightly easier."
