Fuck it can't just SIGNIFICANTLY get better.That is unfair argument against Gavi really and could be applied to just about any footballer at that level.
Motivation doesnt look an issue with him.
He currently looks to have a very immature mentality in terms of decision making on and off ball and fairly limited on ball in terms of vision and range of passing etc.
This should all improve when he calms and plays with a clearer head and not thinking he is the worlds hardest dwarf.
Keeping him in team regardless of how poor he is doent help. He needs to be in and out more.
For example, if you run slow at 17, you won't run much faster at 20.
Yes, you can become a fraction of a second faster through training, but not by much.
For example, Yamal. I say that he is rather slow to become an elite winger. They answer me - he is only 17. WTF?
