Palmer shone in the triumph, with Nicolas Jackson finding the back of the net twice.
"A tough place to come and a good three points, we are happy," he later said.
"Everybody knows he (Jackson) is a top player - he needs to keep going. The Chelsea fans and players rate him highly - we know what he is capable of.
"There will always be noise, we try to block it out and listen to the manager. We have a good manager and it can only help us to get better."
