Manchester City boss Pep Guardiola to BBC Sport: "We play a really good game. In 90 minutes we concede mistakes a little bit, but the way we played was really good.
"Luck doesn't exist in football. We have to score goals and we didn't do it. We played to score goals and concede few. We struggled a little bit.
"The guys who were playing were playing good, that's why I didn't make changes.
"We didn't score, that was the mistake.
"The team that was there today was there before and will be there in the next game. I am very pleased with the performance and the way we played."
Crystal Palace boss Patrick Vieira to BBC Sport: "It was a difficult game. I was really pleased with the players. We worked hard, we worked well. We defended well and created a couple of chances. I’m happy with the team spirit and organisation today.
"When you play against City you have to concede chances. It’s all about having your luck on the day but also putting in a shift as a team. We did that today. We fought for the luck and we got a point. We’re happy with the performance.
"[I was happy with] the way we managed the game. We defended well as a team. At times during the season we’ve struggled during difficult periods. But today we stuck together.
"We had some chances. It was that kind of feeling you can score one and win the game 1-0. I’m happy with a draw.
"Part of the game we have to learn and be more consistent if we want to be a better team. You need to roll your sleeves up and defend well and today we did that.
"It’s all about building confidence. Playing against City and not conceding is always positive. There’s a lot of positives to take to the FA Cup game."
