Harsh because he's a young lad and I'm sure that had Casemiro or Eriksen been hooked, the reaction would have been the same
However...he's a very strange signing. No obvious position, not a goalscorer, not a #10, no pace, not aggressive.
You look at his profile and his goal record...he's not getting into a very average Holland side ahead of Wout Weghorst...alarm bells were ringing.
He's the kind of slow moving technical football that can only really do well in Holland and Serie A. He has some positive attributes but the games far too quick for him.
I feel sorry for him that he was given that reception, really whoever OKd the signing should be taking that heat.
