Jack Grealish pictured partying in his full kit the morning after winning the Champions League

Manchester City star Jack Grealish has been out celebrating the club’s Champions League victory and was pictured partying in his full kit at 5 am on Sunday morning.

The Citizens were crowned champions of Europe for the first time ever on Saturday and secured the treble by beating Inter Milan 1-0 in Istanbul.

The full-time whistle sparked celebrations from fans and players alike with party animal Grealish appearing on social media throughout the night enjoying the celebrations.

A 68th-minute goal from midfielder Rodri secured the one trophy that has eluded manager Pep Guardiola since he took charge at The Etihad and emotions were high.

Grealish broke down in tears when being interviewed by BT Sport as he talked about his family, and labelled Guardiola a “genius”.

"To win the treble with this group of players is so special. This is what you work your whole life for. I am so happy," he said.

"He's just a genius [Guardiola], isn't he? I just said to him then, 'I want to thank you because you've made this happen for me'."

Celebrations continue

The celebrations continued long into the night with a group of first-team players including Grealish pictured still partying the morning after the final.

Whilst a lot of his teammates appeared to have changed clothes, Grealish was still wearing his full kit from the game indicating he hadn't yet gone to sleep.

When he joined City for a British record £100m back in 2021 there was a lot of expectation placed on his shoulders and he struggled at first.

However, this season he has been an influential part of the club's treble success making 46 appearances and being directly involved in 16 goals.

"He put so much faith in me [Guardiola], buying me for a lot of money. Even last year, when I was playing c**p, he stayed there with me [and] spoke to me," Grealish added.

"And then this year, he's given me that platform to go and perform. I just said thank you to him."

Given the enormity of the achievement, it's likely the celebrations will be non-stop over the next week and it continues with an open-top bus parade around Manchester on Monday.
