They will need some rigorous testing along with some rapid results if this is to be done safely. There's still a small number of players being diagnosed but if one slips through the net, two teams along with their staff at just one fixture could all be affected and this could go back to their families. I'm not sure how they are doing it in Spain, Korea and Germany but it does seem to be working but those countries seem to have solid strategies in place and none of their footballers have been done for violating lockdown rules.
The football league needs to get its arse into gear - at this rate they will still be consulting with clubs in the year 2029 for this season!
