Manchester City became the first men's team in English history to win the domestic treble on Saturday. A 6-0 win against Watford at Wembley secured the FA Cup, which Pep Guardiola's side have added to their League Cup win and Premier League glory. David Silva opened the scoring inside the first 30 minutes before Gabriel Jesus added a second before the break. The final was effectively over on the hour mark when Kevin De Bruyne made it 3-0 before Jesus struck again. Raheem Sterling added a late brace to secure the domestic treble in style. 

There was an awful lot for City to celebrate at full-time as they rounded off a brilliant season and one man who appeared to enjoy the result more than most was the club's kit man.

Brandon Ashton, who's already perhaps the most famous kit man in the country, was filmed going absolutely wild in the dressing room at Wembley. 

Wearing just his underpants, Ashton was caught on camera bouncing around the room spraying everyone with champagne, diving into the laundry basket and belly sliding across the floor.

Class. Of course, he wasn't the only one who was very happy with City's FA Cup win.

After the game, Guardiola declared that winning the domestic treble is harder than winning the Champions League and said that this has been one of his best seasons as a manager. 

"I love the Champions League, but to [win the domestic treble] is more difficult than to win the Champions League," the City boss said. 

"It's one of the best seasons I have experienced as a manager. I wouldn't say the best, but one of the best for sure.

"To be the first to win the treble means that if one team is able to do that then another team will repeat it sooner or later. Winning four titles is something incredible."
