I mean, some would say that players should perhaps be taking a hell of a lot better care of themselves when it comes to catching COVID. If your job is to get paid insane amounts of money then I don't think its unreasonable to expect your entire life to revolve around that up to a point. In the grand scheme of jobs, footballers have a ridiculously easy life at the top level. They don't work every day, they don't work 8 hours a day. If they get injured they get time off bar rehab and they get paid more in a week than a lot of people get paid in a few years.
The vaccine is here and until they get vaccinated I think they should be quarantined together and very very strict measures put in places to protect them. Considering what some footballers have been doing during COVID times and then catching it, its not like they are doing everything in their power to stay safe.
