The Rs face Tottenham tomorrow in another London derby.
The ex-Cardiff striker told The Sun: "It was a great win against Chelsea. It was very disciplined and showed our team strength and togetherness.
"If we don't go into the match with Tottenham thinking positively then what happened against Chelsea doesn't mean anything.
"There was a great feeling in the dressing room. Neil said it was the kind of performance he wants to see every week and we have to replicate that again."
