This is a well thought out piece from Martin Samuel. He is arguing that rather than Jose bullying Shaw, it could be viewed as a more tough love approach that has always been used in football, and cites various examples. He also highlights how Jose at times has spoken positively of Shaw and tried to sign him for Chelsea, so perhaps Jose does really rate him but is disappointed with his commitment, and knows he is capable of much more.
Personally I agree with this view. I think Jose rates him, but we don't see training every day which is where he is obviously feeling Shaw could be doing a lot more. And when Shaw was pulled off at half time the other day, he wasn't bad but he wasn't exactly pulling up any trees either. That might be where the issue lies, that while Shaw put in a decent but not great performance, Jose knows he can do a lot more and feels that he isn't showing that.
Maybe the truth is somewhere in between Shaw needing to show more commitment to Jose and take on board what he is being told, and Jose needing to lay off a wee bit, but ultimately the future is down to Shaw himself. It's fight or flight time, and his decision will tell us a lot about him. I think bullying accusations are OTT.
