Manchester City are no strangers to dressing room celebrations at this stage and they proved that by performing some more wild antics after their FA Cup triumph.

Pep Guardiola‘s side secured a domestic double on Saturday afternoon after Ilkay’s Gundogan’s brace ensured a 2-1 win over rivals Manchester United at Wembley.

And despite the fact City still have the Champions League final to play in one week, they wasted no time in letting their hair down and enjoying the win.

Plenty of City’s stars took to social media in the minutes after the match to share the celebrations with supporters and fans online – and it didn’t disappoint.

England star Jack Grealish showcased a video of club kitman Brandon Ashton ᵴtriƥping down to his boxers and sliding across the changing room – which has become a tradition among the side.

In Grealish’s video, Ashton slides all the way across the room – while being cheered on by City’s celebrating stars – before crashing into Grealish’s seat.

The former Aston Villa winger quickly looks down and yelps: ‘Oi, watch my Gucci bag! F****** hell’ before picking up his backpack and continuing to celebrate.

Another video posted by Grealish quickly did the rounds on social media as it showcased the forward drinking a beer and saying: ‘Get it down ya!’

City’s stars were clearly in a good mood post-match and were seen walking towards their dressing room in high spirits.

In that video, England full-back Kyle Walker can be heard shouting: ‘Get the music on’ as they approach the dressing room and begin to start the celebrations.

Elsewhere, City goalkeeper Stefan Ortega – who was chosen ahead of typical first-choice Ederson – shared a picture alongside two John Stones and Kalvin Phillips with the caption ‘Warzone boys’.

Many would’ve been eagerly anticipating the reaction from City’s talisman Erling Haaland and he certainly sent his message to supporters with a post online.

The Norwegian striker shared a picture of himself alongside Grealish and the FA Cup trophy with the caption ‘2 Down… 1 To Go’.

Pep Guardiola’s side will face Inter Milan on the June 10th in the Champions League final, where they could secure a historic Treble.

The match at Wembley was settled after a thrilling encounter between the two Manchester giants.

German midfielder Gundogan opened the scoring within 12 seconds – the quickest in FA Cup final history – to give City an early lead.

But, after a hand-ball call on Jack Grealish, United were level thanks to a converted penalty from Portuguese playmaker Bruno Fernandes.

However, despite United’s best efforts, it was City who came out on top thanks to Gundogan’s second goal of the game – an awkward volley that bobbled into the net.
