The saddest is the abuse directed at people who are prone to injury.I agree entirely.
I get fed up of people criticising players BECAUSE they suffer injuries.
They spend hours stretching, massaging , warm ups ,warm downs, trying to protect themselves, but inevitably any elite level sportspeople have to endure injuries.
It is having the professionalism to recuperate and return to the top level that is critical.
Gundoghan is perhaps the finest example.
For most players, being out on the pitch will be the highlight of their life, and it'll be over by the time many of us are just getting ahead in our careers. To never fulfil your potential, miss years worth of games, or retire early because of injuries must make them feel shit - yet they get casually abused all the time, and so many fans genuinely think badly of them.
