There's definitely an element of well, Mourinho has implied it so it must be true on here right now. Whether it be Mkhitaryan, Shaw, Martial, now both Smalling and Jones. Jones, in particular, has never had a bad word said about him by any manager he's worked under. Infact, when fit, they've often done their best to get him straight back into the team.
Yet Mourinho makes yet another needless remark about fitness and all of a sudden there's suggestions on this forum that they're both softies. Uncommitted and stealing a living for too long, or something.
I can't subscribe to Martial being actively lazy or uncommitted. He clearly ran more on Sunday, but how much of that is to do with the position he was played? No doubt Mourinho knows how to motivate squads; he's made a career by doing so. But every insinuation that is made isn't necessarily as sinister as conveyed, and some (even his biggest supporters) would do well to remember that.
