My point was that no manager go against the will of both the physio and the player. The manager need the accept from 1 of 2, and physio will accept play if he assess that playing doesn’t make the niggle worse.
If I don’t remember wrong it was a lot of speculations when Martial didn’t join the squad a couple of matches. Like both the manager and physio thought he was ok to play some minutes, but Martial didn’t want to play. If that was true, Martial, actually did decide himself.
I suppose Martial agreed to play when he did, and credit to him for eventually “take one for the team” if he didn’t feel 100%. Martial’s main point in my opinion is that he missed official backup from Ole when he performed badly; he wanted Ole to explain and excuse his performance, but hey, which manager go public and tells opponents his player isn’t up to full speed? A bit stupid if he have to play him some minutes next match.
Martial have to find other ways to cure his performance anxiety. A manager shouldn’t go public and excuse players performances, and neither should the player.
Managers can go against the will of both the physio and the player. He has the final decision in if the player plays or not, not the physios, and certainly not the player. They can advice him but he's not in any obligatory need to listen to them.
