City came out top of the league at the Etihad Stadium on Sunday after a 3-2 comeback win against Aston Villa and the festivities were in full swing the following day as the team relished in their success with an open-top bus cavalcade through Manchester.
And all eyes were on Grealish, who was signed to the club last year for £100 million and also played for the Republic of Ireland’s minor squads, who could be seen glugging beers as he partied with his teammates on the bus.
The 26-year-old was also heard playfully mocking his teammate Bernardo Silva during their tour of Manchester’s streets.
Speaking hoarsely into a microphone while wearing City’s iconic sky blue kit, Grealish said: “It’s been brilliant to win my first title. I want to thank everyone, but the main person I want to thank is Bernardo Silva for coming off in the 70th minute because he was miles off it yesterday!”
The Birmingham native’s jibe sent his Manchester City and England teammates Kyle Walker and John Stones into hysterics.
Portuguese midfielder Silva was quick to hit back at Grealish, teasing: “Keep Jack Grealish on the f***ing bench.”
The midfielder later videoed himself singing passionately along to Queen’s We Are The Champions while wearing a pair of snazzy sunglasses and a scarf adorned with his face.
And as the club’s players were called up one-by-one in front of thousands of fans, Jack strutted onto the platform with a bottle of beer in one hand and a Jagerbomb in the other.
After the former Aston Villa star’s antics on Monday, some brands took to social media to see if he needed any help recovering from his hangover.
The official Dominos Pizza UK account tweeted the footballer saying: “@JackGrealish… need a pizza much today mate?”
Grealish wasn’t the only one in a party mood on Monday either, as Premier League Player of the Year Kevin De Bruyne lapped up the victory and said: “I'm a little bit drunk! It's amazing to do this for the fourth time.
“We couldn't really do it last year because of Covid, but it's amazing to see so many people here to celebrate with us. Thank you to the fans, the last game and atmosphere was amazing. Enjoy the summer and let's go again.”
