I thought he was pretty good until the 60th minute and then he successfully overplayed and overthought everything. Needs patience and time though he's raw.
He played well overall, looked gassed in the second half and had some terrible touches. His finishing will come, looked like an alright finisher at Braga.
The potential is there but I don't know if he will realise it here. There's an awful lot of pressure at this club and even experienced players find it hard here.
He seems to me that it's very close to his left only, and for that reason he is not a good winger for the right. I would try him on the left (the problem will be when Fati returns)
He is always bad as a sub, especially when we need a goal. Been several times this season already. Should only start vs weaker teams or come on when we are leading.
