like pogba?
if we dont get him more chance for play his improvement is slower and never reach his talent value
I don't think we should use the best young footballer in the world as the standard for what is "normal", when developing youth, though. Pogba's rise has been meteoric, and it would be unwise to expect others to develop similarly. Paul has a blend of explosive physicality, technical prowess, and maturity, that is very rare. Very, very rare.
Coman played something like 2 substitute appearances in France last season. He's already above double digits in games played, has scored, has played in the Champions League, and is training with top class players and managers, in a top class environment, every day. When he goes to play with the U-National team, he dominates.
I'd say his minutes have been ok this year, all things considered -- look at where the team is. They'll have to decide if he's progressing well enough for them, but again, his comfort level could take a significant jump between season 1 and season 2, as could his training regime. He could return bigger and stronger, with more confidence, and a much better understanding of what Max/the team require of him.
He's got a lot of potential, and he does need to play, but I'm interested to see what Beppe decides to do in the off-season. There are a lot of questions about our forward line for next season, and Coman may be able to earn solid minutes at Juve (depending on who leaves, who arrives, tactics, etc).
