The footballer, 27, was busy filming the locker room post match mood when the team’s kit-man got a little too close for comfort to the midfielder’s swag.
In celebration of their second trophy of the season, the team gathered and wet the floor as their kit-man readied himself to take a slide across the club’s badge that was imprinted into the tiles.
Egging him on, he shot onto his stomach and slide right into the locker room bench that was against a wall beside where Jack was filming for his Instagram Stories.
The kit-man – Brandon Ashton – decided he wasn’t quite finished gliding around the room and with the encouragement of the team, removed his shorts and slid underneath defender John Stones’ legs.
Crashing harder into the same spot beneath Jack, this time his landing wasn’t as smooth and his wet body slid straight across the former Aston Villa captain’s beige Gucci backpack.
‘Aye watch my Gucci bag f**king hell!’, Jack was heard exclaimed from behind his phone as he hurridly reached down and snatched the designer item from the floor.
His prized possession – a beige branded rucksack that featured metallic Gucci symbols on the front – could be seen at the end of the clip as the star held it up to wipe it down and rearrange the straps.
Posting on his social media account, Jack saw the funny side and added a string of crying emojis underneath the kit-man’s tag as he shared what happened with his seven million followers.
Acknowledging the meaning of the defeat, the team’s manager later reflected on why it was a special day for the team – Jack included.
Pep Guardiola said: ‘A final against United is always, for many reasons, difficult but the better team won. We are humble enough to accept how good they are and we did it. We’re really pleased.
‘Winning the FA Cup, the emotions are so, so special and to celebrate with our people, it is really great.’
