Chelsea boss Jose Mourinho says Crystal Palace deserved their win at Stamford Bridge.
The Eagles were triumphant, stunning the hosts just when they thought Radamel Falcao had got them back into the game with his first goal for the Blues.
Joel Ward popped up to restore the lead, after Bakary Sako's opener, as Palace earned a 2-1 win, their first at Stamford Bridge in 33 years.
"The first thought is to Palace," Mourinho said.
"They come with everything. They were lucky but they deserve the luck.
"My team, I think we deserved more. I don't want to say we deserved to win, because it's not true.
"The referee did a big mistake. Clear penalty with the result 0-0 and obviously with influence in the result.
"The one with Zouma that I watch at half-time on television. It was a clear penalty.
"(But) I prefer to go in this order, when I say Crystal Palace first."
