Hamburg's Lewis Holtby believes that wonderkid Moussa Dembele will leave Celtic for a bigger club in the foreseeable future.

Dembele joined Celtic from the Cottagers during the summer and the 20-year-old has set Parkhead alight with his fine performances, scoring 13 goals so far for Brendan Rodgers' Hoops.

Dembele's ex-Fulham teammate Holtby is not surprised by the youngster's exploits at Celtic and has now tipped the Frenchman to soon move on from the Glasgow giants.

Former Tottenham Hotspur midfielder Holtby said: "In Dembele, Celtic have a real threat as he proved against Manchester City (in the Champions League).

"I played with Moussa at Fulham and he's a big talent. A lot of good things have been said about him and it's all justified.

"I knew the first time I saw him he was a bit special. He was very young at Fulham when I was there, maybe only 18. But you could see his power even back then. He's so strong and has an eye for goal. He can bury chances. He's proved that already by scoring goals against City.

"I really believe this could be his last season at Celtic if he keeps scoring goals. Everything is rocketing for Moussa right now. He's scoring for Celtic and France's Under-21 team.

"He has a great manager in Brendan Rodgers, who knows how to keep young players determined and Moussa's got that. He'll go on to have a great career, there's no doubt about that."
