Palace fell behind to a well-taken Jermain Defoe brace but came storming back into the game in the second half.
"That is a massive win," he told the BBC. "We knew it wasn't going to be easy here but we showed in the second half especially great character.
"As a striker you have to be patient - I knew a chance would come.
"We wanted to win this game, we are in good shape and hopefully we can keep it going."
