So most of the time we see his bad actions and stuff that does not encourage anybody to believe he can play the central role in attack besides Messi.
He is no lost cause and a few upcoming games will decide if he has had a successful season.
He has never been a No.9 so it's irrelevant if he plays that role with Messi, simply because he's not meant to do that role.
He is - unfortunately - not capable of doing that.
The main problem with him is his lack of qualities in certain aspects, like dribbling, pace, strong-one-footedness, good but not outstanding creativity, and the like.
Comparing his qualities (and his rapidly growing age) to any attacker of the good MSN time, is just a joke in itself.
But he is diligent, hardworking, not injury-prone, isn't a bad finisher, etc. But comparing Griezmann to his predecessors in Barca is unfair because he is NOT such a great player.
Wanting or waiting for Griezmann to SAVE the present Barca attack is a delusion in itself.
