In other sports, like say American football, albeit in a much compressed season, players are literally destroyed by playing with injuries for which they should be in hospital. Players are physically abused by coaches and medical staff, but it seems to be part of the "sporting" culture.

I posted the following earlier.
In the scenes between Mourino & our Head Medic Geoff Scott, I couldn't help thinking of Eva Carneiro. That whole incident when she ran onto the pitch to treat Hazard is one of Mourinho's all time worst moments. For a master psychologist, he got both the original incident and its protacted aftermath catastrophically wrong.
But I gained an additional perspective from the Sonny arm fracture scenes. Mourinho seemed angry, genuinely furious, because an injury was "destroying his work", sabotaging his team. He is so driven, and expects his players to give so much, that he tells a story of when he played with a serious arm injury. And in his mind, he thinks Sonny would also do so if the medical staff permit it. Which is probably true.
Mourinho's driven competitive nature sees medical staff as an impediment, getting in the way of his task. But ultimately medical staff should, and must, put the player's welfare first.
