Palace is competing in its third FA Cup final, having lost to Manchester United in both 1990 and 2016, against seven-time winner Manchester City at Wembley Stadium on Sunday (AEST).

The Eagles have beaten Fulham and Aston Villa on their way to the showpiece match, but face a difficult test against Pep Guardiola's side.

Palace is without a win in its past seven games against City, losing four of those, since a 2-0 win in the Premier League back in October 2021.

But Glasner's team has impressed in the FA Cup this season, conceding just once in the competition while scoring exactly three goals in each of its past three matches.

With history beckoning for Palace, Glasner called for cool heads from his team, likening this fixture to Brazil's humbling semi-final defeat against Germany at the 2014 FIFA World Cup.

Brazil was beaten 7-1 in that match, sinking under the weight of expectation, and the Palace boss believed that taking the emotion out of the game will be key for his players this weekend.

"Yes, this would be reward for an outstanding FA Cup journey, but I don't really think about the trophy," Glasner said.

"I can remember the [FIFA] World Cup in Brazil, and the Brazilian players were crying during the national anthem because of all these emotions that they wanted to give back to their country, winning the [FIFA] World Cup at home, and they lost 7-1 to Germany in the semi-final.

"We shouldn't feel pressure to bring silverware to Crystal Palace because this has never happened in the club's history. We will give our best. This is our mindset tomorrow."

City has won its past three FA Cup meetings with Palace by an aggregate score of 18-4. The most recent meeting was in the fourth round in 2016-2017, with the Citizens winning 3-0 at Selhurst Park.

Palace comes into the clash as the underdog, with 16 points and eight places separating the two sides, but Glasner's team can come into the contest with confidence.

Its victory over Tottenham Hotspur last time out saw it equal the club's record Premier League points tally of 49 with two games of the league season remaining.

"Our preparation was more or less the same as for a Premier League game," Glasner added.

"We focused on what we wanted to do. We analysed Man City, but 90 per cent we were talking about us because this is what we can influence. 

"The players did very well in the last couple of weeks, and we have a lot of confidence, looking forward to the final."

Glasner also confirmed that he has a fully-fit squad to pick from, with midfielder Adam Wharton available again after missing the win at Spurs last weekend.
