Could some players still train?
I'll start this by saying that I'm not suggesting any players should be forced to go to work in an unsafe environment.
Could training still go on in a much resistricted way at the training ground? Not in the gym for obvious reasons , but on the field, with limited numbers and sessions, but surely better than nothing.
The current govt advice is that you should work from home if you can, and to go to work if you can work while observing the 2m distancing rule - on the face of it that would cover professional athletes training.
