Ward has admitted that his side now want to better their result of earlier in the season when they were narrowly defeated by City at the Etihad Stadium.
He told the club's official website: "I think in the first game at their place we were unfortunate maybe not to come away with at least a point really.
"We had a few good chances late on, but if we can prepare like we have in any other game and make sure we look after ourselves and prepare right, at the end of the day it's 11 against 11 on the pitch and anything can happen.
"We want to continue our form right until the end of the season."
Palace are 11th in the Premier League with 43 points after 35 games this season.
