I'm afraid this just underlines what Pulis does to players. He can't recognise genuine skill, or if he can, he makes the player compromise so much, that it takes the edge off what he's best at. If we'd had Messi under Pulis, he'd probably have been in and out the team if he wasn't tracking back into the defensive block. And Messi probably isn't that good at tackling.
l watch alot of German football and Gnabry has everything you want from a striker. I'd love to have seen him managed by Billic.
