Palace boss Patrick Vieira feels that if they want to maintain picking up results like the one against Man City, they will have to keep pushing for each other.
At Selhurst Park, the Eagles put in a solid effort to keep Manchester City to a goalless draw.
The Eagles have now preserved a clean sheet twice against the Champions this season, the first time being a 2-0 victory earlier in the season.
As a follow-up to their spectacular 2-0 victory against Wolves, the Eagles’ persistence against the Champions was particularly noteworthy.
The Eagles are currently 11th in the Premier League standings, avoiding a relegation battle and aiming for a first Wembley appearance in more than a decade.
But their boss, who was clearly ecstatic about his players’ performance against Pep Guardiola’s team, lauded them but stressed that they had to keep up the effort if they were to continue to outperform their opponents.
The Palace boss said: “We need performances like these from everyone from starting from the goalkeeper through to JP who played on top and later when Wilf went on top.
“They run alot and they run for each other and we played for each other and we showed that we were improving as a team.
“One of the challenges was to accept that we were not going to have the ball and once we are doing this we will grow as a team which pleases me alot.
“This is a big result for us and the FA Cup is a massive Cup for us and going into the game on the back of massive performances like this will help but we need to prepare well for that and continue to be there for each other, we have to always be ready.”
