Former Celtic star Olivier Ntcham has revealed he left the Hoops because he became bored winning every trophy.

And he's admitted he left the club under a cloud.

The Cameroon international midfielder spent four years at Parkhead, although he joined Marseille on loan for the last six months, before moving to Swansea City three years ago.

Ntcham, who moved to Celtic from Manchester City, is now playing his football in Turkey with Samsunspor and the 28-year-old has revealed the unusual reason why he decided to leave Celtic.

He said: "I left Celtic because I didn't think I could win any more trophies with them at the time.

"I was there for three seasons and we won everything, all the trophies. So I thought it was the right moment to leave.

"But I had some disagreements with the club because they didn't want me to leave.

"I left anyway and because of that, we had a very bad relationship. But I don't have any bad thoughts towards Celtic.

"At the end of the day, this is football and football is like that sometimes. I wish them the best and I was very happy while I was there."

And Ntcham - who won eight trophies in his time at Celtic - admitted he will always cherish the memory of scoring the only goal in an Old Firm game in 2018, where his second-half strike inflicted Steven Gerrard's first defeat as Rangers manager, at Parkhead.

He recalled: "It was incredible, it felt amazing to score the only goal.

"There are no words to use for this type of game, but it was great. The feeling, the stadium full, everything.

"The stadium was shaking and the moment I scored that goal was incredible. It was an amazing feeling and even now I struggle to describe the excitement.

" I felt like we were going to win the game that morning. At that time we played a style of football where we spent a lot of time with the ball.

"I knew we would create a lot of chances and I thought I could score a goal or two.

"So I knew that we would win that match and that I would do something."
