I thought that testing capacity was over 100k but there currently wasn't the demand for it?
I disagree with the above posters. Football is coming back, whether we think that's morally acceptable or not. The UK gov has been making it clear that it wants professional football to return as a boost to the country. We'll be living alongside this virus for months if not years to come, so it's a decision of when football returns and not if. Yes, there's a risk - but there's a risk for everyone being asked to return to work around the country too. The government and sporting bodies clearly feel it's an acceptable level of risk.
As I say, we can debate whether we think mid-June is the right time but now that this ball is rolling I don't think it will stop.
