I think anyone who has genuine concerns about their health in the work environment situation, need to raise them. Its just that footballers are not a key workers, whereas NHS, care home staff etc are. That's why the latter need extra protection in terms of PPE, masks etc.
Deeney strikes me as a bloke who is not a yes-man who just goes with the flow. He is probably speaking for others who don't like putting their head above the parapet. At the end of the day, if he feels uncomfortable playing and training with the health risks, its his decision. Playing football is not that important in the current situation.
