I've no idea if he has a bad attitude or not but I don't think any manager has the ability to always get things out of players who are not mentally right. Pep has transferred out plenty of talented players who he has not fancied for whatever reason and I suspect sometimes it has been mentally.I
Pep is so well respected, that its impossible to fathom the possibility of a bad attitude being tolerated. Shaw will bow down and be grateful for the opportunity if he were to come here. I can't see his attitude being a problem.
