You guys will have a hell of a striker in your hands, maybe i can give you a bit of an insight(considering i watched all of his games for juve):
The guy is a beast, what he thrives on is mostly counteratacking football and you will be suprised how pacey he is and how good he moves off the ball. But what really makes him great player to have in your squad is he is clutch af, big game player and i can assure you he won't hide in those derbies. I think he will suit perfectly into Mourinhos playstyle, considering he also tracks back and contributes in deffence. TBH i was a lot more frustrated of the loss of Morata and Vidal, than i was when we lost Pogba, so that should speak for itself.
Anyway a lot of you that havent watched him and judge him only on his stats will be in for a big suprise!
