Anyway,
Early days but so far the Premier league have been able to do some pretty comprehensive testing:
Round 1: 17-18 May - 748 tested, with six testing positive from three clubs.
Round 2: 19-22 May - 996 tested, with two testing positive from two clubs.
Round 3: 25-26 May - 1,008 tested, with four testing positive from two clubs.
Round 4: 28-29 May - 1,130 tested, with zero testing positive.
Round 5: 1-2 June - 1,197 tested, with one positive result from one club.
In other words, 0.003% of the tests returned a positive sample.
