To think there are some who question the FA Cup. While it may admittedly take a back seat to other tournaments such as the Premier League and Champions League these days, there's no denying that it's a magical, classical event for the United Kingdom and a staple of the footballing calendar.
Days like this are proof of that. Crystal Palace went into their clash against Manchester City as underdogs, with just about everybody expecting Pep Guardiola's side to turn up and sweep their opponents aside.
Except, Oliver Glasner's side didn't read the script. They have triumphed in the competition for the very first time, having previously lost finals in 1990 and 2016. In the end, it was third time lucky. Europe, in addition to the trophy, now awaits.
City dominated the early stages, displaying some intensity that hasn't always been there this season.

However, they found themselves behind after 16 minutes - with Eberechi Eze expertly sweeping home following a pinpoint delivery from Daniel Munoz.
It was a sensational strike from Eze, who played amid interest from City, Arsenal and Tottenham. His goal will have the three sides on red alert, with the former QPR star getting better by the season.
Minutes later, there was controversy.
Dean Henderson came charging out of his goal, with the Eagles goalkeeper parrying the ball away.
He clearly was outside of his box but, following a VAR check, he was allowed to stay on the pitch because the ball was going away from goal.
Not everybody will have the same stance on the matter.
Wayne Rooney, and many City fans on social media, fumed over the incident. The BBC pundit said it was time for VAR to go, while also questioning how they could get things 'so wrong'.
City looked as though they'd be able to draw level when they were given a penalty following a foul on Bernardo Silva.

Erling Haaland stepped up, ball in hand. However, in a shock U-turn, he then decided to pass on the responsibility to Omar Marmoush.
Marmoush had missed one of his seven previous spot-kicks. But he was superbly denied by Henderson, with the goalkeeper diving to his right to keep the Egypt international at bay.
City went into the break hoping to come out galvanised.
They again dominated the early stages of the second half as they desperately hunted an equaliser that would get them back into contention.
