WWE wrestler CM Punk has been spotted inside a Celtic shop ahead of tonight's Clash at the Castle show.

The sports entertainment company host their first-ever Scottish premium live event at the OVO Hydro tonight with hometown favourite Drew McIntyre in action.

The diehard Rangers fan has been loving his time in Glasgow and has proudly donned a Rangers shirt during promotional events.

However, it appears WWE rival CM Punk - not scheduled to be on the card in Glasgow - could surprise fans with an appearance.

And in a clear dig at McIntyre, the wrestler could even wear a Celtic shirt having been pictured with a fan inside a club store holding a home shirt.

TikTok account Weekly Wrestling Rundown posted a shot of CM Punk in a Celtic store with the caption: "I JUST MET CM PUNK IN GLASGOW 🏴󠁧󠁢󠁳󠁣󠁴󠁿
