I think the likeliest scenario is that he has historically been used to low intensity training, and barely pressing in games. Since ETH came, the training intensity has been through the roof, as has the pressing demands on the forwards.
Anyone who says he doesn’t give 100% when he plays, is cross eyed or has an agenda. Even ETH himself has said how hard he presses, and how important he is for the team. The problem I believe is that he’s gone from this incredibly low intensity environment, where he was virtually surplus to requirements (out on loan last season), to high intensity and a central figure. His body just hasn’t adjusted and he’s picking up tons of soft tissue injuries. Whenever he’s played this season, he has worked his socks off. He just can’t stay fit.
All the comments about him taking the piss or stealing a living, are the comments of mouth frothing idiots. However, the reality is that if his body can’t adjust to this training and playing intensity, and he’s constantly injured, then you have no choice but to replace him in the squad. I think that’s very different from being angry and vitriolic towards him, for being injured. If Martial wasn’t putting in the effort, ETH wouldn’t talk so highly of him and wouldn’t even put him on the bench, let alone make him a central figure in the team. There is overwhelming evidence to back that up.
So people just need to cool it with the hyperventilating hatred. I appreciate the frustration. I’m frustrated too. We are much better with him in the team. And if he can’t stay fit, he’ll have to be replaced in the summer. But the suggestions this is some Machiavellian plan to steal wages or be lazy, is just preposterous.
