Chelsea boss Jose Mourinho was full of praise for Crystal Palace after they caused a major upset at Stamford Bridge on Saturday afternoon.
The Blues suffered one of their most shocking defeats at home in recent seasons as they went down 2-1 to Alan Pardew's men.
It puts them eights points below leaders Manchester City, much to the disappointment of the Portuguese.
"The first thought is for Palace," Mourinho told reporters.
"They come with everything. Team ready, players ready, fans ready, fantastic spirit.
"They were lucky, but they deserved a lot. I think we deserved more, but not deserved to win.
"I cannot say I had 11 players at the same time performing. To be fair, two or three of them, individual performances were far from good.
"I blame myself for not changing one of them, because I kept him in the game for 90 minutes. When I made the third change, I realised I needed a fourth.
"If a player is not performing, there are two ways: trust the player and wait for improve, or... have to change. I can go both.
"Finally, the referee, with a big mistake, a clear penalty [on Kurt Zouma] with the result at 0-0."
