Former Celtic star Georgios Samaras is "100 percent sure" Matt O'Riley will leave the club this summer.

The ex-Parkhead forward is certain O'Riley is set for a big-money move at the end of the season after seriously impressive performances for Celtic.

For Samaras, there is no doubt that O'Riley is capable of performing in the top leagues around Europe having developed every season in Scotland since his arrival from MK Dons.

Samaras exclusively told Ladbrokes Fanzone: "I'm 100% sure Matt O'Riley will leave the club at the end of this season. He's out.

"He had a great season last year, he's had another fantastic season this time around, and we're clearly seeing him develop year on year.

"He came from League One in England and he's giving his team something every single week... he's so talented. His goals, his assists, his general performances... I think he's at the peak of his Celtic career.

"Now, the best thing for him, and the club, is to go and find the best offer for him in the summer."

The Parkhead fan favourite added: "He can play in any team, that's for sure. OK, it would be more difficult to play for any of the top four in England, and he's probably not ready yet to join those clubs - but I have no doubt in his ability to go and perform at a similar level in the Premier League. It'll be a case of who can afford him... 

"Celtic have a very expensive asset in Matt O'Riley, so I've no doubt they'll get a huge transfer fee for him.

"And I'm not just talking about the Premier League, by the way; this is a guy who I could see in Spain, Portugal, Germany, Italy... any of their big clubs, I can see him going and standing out anywhere in Europe."
