Garnacho is younger than Amad, yet streets ahead in terms of development, decision making and aptitude.
Amad has a huge amount of growing up to do which is strange considering he's 22 years old now.
Put it this way, Gravenberch is the same age yet his decision making and development is way in excess of Amads.
There's only so much leeway someone can get, he's now close to 90 appearances in senior football and whilst everyone develops at different ages, I don't think United can rely on Amad whilst he is currently still not making the right decisions during games.
