"We are looking forward to the game and see it as a chance to put things right after the first leg.
"It means nothing. We are going to play a game of football, it doesn't matter what has been said. We've got a good mentality. That showed against Blackburn and on Saturday when we were 2-1 down against Portsmouth and went on to win in stoppage time."
Cardiff are currently third in the Championship, while Palace are 14th.
