Salomon Kalou says victory at Everton last night is proof Chelsea are united.

"After Monday against Wigan, we had to come back strong, because we know that if we didn't win today it was almost over - but we decided to fight until the end," Kalou told Chelsea's website.

"It started today, I think every player did their best to get the victory, and now we have three more games to go, so we still believe."
