Jurgen Klopp questioned why Tottenham did not have hand sanitiser available in their press room ahead of his post-match comments after Liverpool's 2-2 draw.
Spurs were struck by a large coronavirus outbreak, which saw their fixtures against Rennes, Brighton and Leicester called off and their training ground forced to close.
At least nine first-team players and several members of Antonio Conte's coaching staff returned positive tests, a worrying trend now disrupting the Premier League.
And Liverpool manager Klopp is seemingly eager to remain out of self-isolation, having advised Spurs to introduce new measures inside their stadium for safety.
