A number of Celtic fans were not happy with the Hoops’ latest addition to the club shop after they tweeted a link to a new t-shirt on Monday.

Celtic uploaded a photo of Jeremie Frimpong holding up his very own ‘Oh My Days’ t-shirt on Monday, with the tweet revealing they are now available to buy either online or in the official club shop.

Frimpong has enjoyed a hugely successful campaign following his move from Manchester City, with Scott Brown suggesting he could follow in Kieran Tierney’s footsteps and earn a big money move in the future (The Herald).

Furthermore, he has been a hit with the supporters as well, with many praising his attitude and personality following the post-match interview he gave after the League Cup final win over Rangers.

And his use of the phrase ‘Oh My Days’ in that interview was also noticed by SPORTbible, who described it as one of the best interviews they’ve seen.

Celtic have now released a t-shirt worth £22 with ‘Oh My Days’ in bold letters on the front, revealing the news on Twitter, but these fans were not happy after seeing the post.

Are you a fan of Frimpong's t-shirt?
