Charlie Nicholas claims Odsonne Edouard "irritates" him - because the Celtic striker allegedly doesn't celebrate when he scores.
The former Hoops striker believes the Frenchman is the top striker in Scotland - ahead of Alfredo Morelos - but has accused him of looking disinterested in so-called lesser games.
Edouard has scored six goals in all competitions this season, with three of those against sides outside the Premiership's top six.
Nicholas believes the 21-year-old could eventually net Celtic upwards of £25million, but he still has reservations - mainly over his apparent refusal to show emotion after finding the net.
"Odsonne Edouard is the top striker in Scotland but Alfredo Morelos is starting to close the gap," he told The Express.
"The Celtic frontman is a better all-round footballer, although he has this slightly annoying habit of looking too casual and uninterested a lot of the time.
"It's as if he can't be too fussed in the so-called lesser games. The thing that irritates me more than anything is his lack of celebration when he scores.
"It should be the greatest feeling in the world but Odsonne doesn't show that.
"The Frenchman has shone on the big stage and he has a growing composure in front of goal.
"People are already saying he is better than Moussa Dembele, who left for £20m but I'm not so sure.
"For me, Dembele has more cunning and aggression in his game.
"However, I can see Edouard continuing to improve and leaving Celtic in a year or so for at least £25m.
"Edouard and Morelos are top-class players and we should cherish them while they're in the Premiership."
