My point is that at least in some cases it is a feck up from a medical/managerial team and they should have never been cleared in the first place. I don't think you can make an argument that Wan-Bissaka and Licha are players to dodge responsibility when they can and just collect their paychecks and they are the ones I remember off the top of my head.Good point. It is shit how players know they can get away with that at United and turn up again whenever they fancy it.
I remember Hargreaves doing that in his first game back (I think it was vs Wolves) and Fergie never trusted him to start a game again.
This is obviously pure speculation from me, but it would also be kind of expected that when a medical team can not be 100% trusted in those instances that players are going to start taking those decisions into their own hands and probably get some false positives along the way.
