Chelsea boss Jose Mourinho was delighted with victory at Crystal Palace - particularly as it was achieved without Diego Costa.
Mourinho insists his entire team has improved, not just with the addition of Diego Costa.
"There is a general feeling our team has improved because of Diego and Fabregas," said Mourinho.
"And it's right. But, at the same time, this team had big improvement. It was good to have an important victory without the player who has scored so many goals and given us so many points."
