As time ran out, Manchester City ran out of ideas and Crystal Palace held on to seal a historic win for the club.
“It’s special,” matchwinner Eze told BBC Sport after the game. “I don’t even know what to say.”
History-makers
Crystal Palace came into the game as heavy underdogs.
The club had never won a major trophy in its long history and was facing a side which has dominated English football in recent years.
Manchester City has won the Premier League six times since the 2017-18 season, alongside a host of other major honors.

But this Crystal Palace team did not let the history books distract them from the task at hand.
“I think that’s what’s amazing is that we can do something nobody in Crystal Palace history has done,” Crystal Palace defender Chris Richards told CNN Sports’ Darren Lewis prior to the final.
And Crystal Palace did just that, making history thanks to Eze’s goal. The American defender also told Lewis of Eze’s importance to the team.
“He does things out here that nobody would expect – I don’t even have the creativity in my brain to think of some of the stuff that he does,” Richards said of his talismanic teammate.
“He’s one of those guys who leads by example. He doesn’t have too much to say but when he does say it you understand that it’s probably coming from a good place.”
Not only does this win represent a first major honor for Crystal Palace, but the club will now also be playing in Europe for the first time in its history next season.
Celebrations of Crystal Palace fans will last deep into the night after breaking its long drought and will surely now continue around the continent next season.
