Manchester City have been blown away by Celtic rising star Karamoko Dembele, according to Jackie McNamara.

Speaking exclusively to Football Insider, the Hoops legend and former SPL manager claimed the Premier League giants have been amazed by the talent of the 16-year-old.

But the wonderkid’s lack of size is a concern for the main clubs who have been trailing him since he burst on to the scene when handed his Celtic Under-20 debut at the age of 13.

“Dembele looks a talent, left foot and everything else and he’s been like a little man, if you like, at a young age,” McNamara told Football Insider.

“All the clubs are looking at him, like Man Citys, I know other clubs mostly, Man City are like, ‘phwoar’ at 12, 13, 14 but now they’re like ‘nah, don’t think he’s going to do it’.

“He’s little, but he’s been that for a few years now, he’s been that same size when they were all younger so he was like a wee man but nowadays they’re bigger than him and he’s not moved.

“Don’t get me wrong, the player’s there but because he was a wee man at that age (13), he’s the exact same as he was roughly then – strong, powerful left foot, low centre of gravity, but there comes a time – my son’s 15 next month, at that age I was smaller, I’m not a big guy but I was tiny, small, skinny and I got released.”

Celtic announced last December that Dembele, then aged 15, had signed his first full-time professional contract in a deal that ties him to the club until at least 2021.

The midfielder joined Celtic in 2013 and made his Under-20s debut against Hearts in October 2016 – coming off the bench for a side then seven years above his age group.

He has been capped by both England and Scotland at youth international level.
