Your positivity is a breath of fresh air I must say.
Personally however I don't think he's been brilliant. He's been good, very good certainly. As you say, excellent pressing; excellent movement. His link up play is good, but I've seen much better from him for Brazil. Similarly so for his passing.
Last night he suffered positionally. Whilst he's played wide before it's been as a wide forward instead of a natural winger. A bit like Sane at LWB, sometimes it works and sometimes it doesn't. He tracked back excellently, but he kept drifting inside leaving Walker a bit isolated.
He's 20. He's always going to be somewhat inconsistent. Particularly as he's not been able to lead the line on his own as he's best doing.
He's been very impressive this season so far, yes. But on the same note, I'd be somewhat disappointed if this is as well as he's going to play, if that makes sense.
