I loved Hatem as a RW but he's never in a million years a PL no.10. He's worth most to the team basically doing his own thing out wide, not in a role which relies on the movement of and linking up with others. In other leagues where you get a bit more space the no.10 position can be more of a free role. Not the PL, and, as you allude to, especially not in a Benitez system.
