What I never understand is, a player gets injured, is under treatment and is eventually passed fit for training. They, presumably, start with light training and are carefully monitored. They then, at some stage, move up to full training with the first team squad. Finally, they are passed fit to play.
They've gone through many stages and tests before it's decided that they can now play. With Mount that's many months in which he's trained a lot, including intense training to test if he's really ready.
Then, he plays half an hour and gets another injury.
Alright, I get that match fit and fit to play are not necessarily the same things, but how can you pass someone fit to play, after months of rehabilitation only for them to break down again so quickly?
