Thomas Tuchel said he would be furious if rivals have been taking advantage of Covid-19 postponement rules to cover injuries.
It was put to Tuchel that Sunday's North London derby between Arsenal and Tottenham could be postponed with Mikel Arteta claiming to have just 12 fit outfield players in the first team.
Asked if teams are covering for injuries rather than Covid cases, Tuchel said: 'I strongly, strongly hope that is not the case because I would be very angry.
'We are doing everything to make games happen and we were made to play when we thought we maybe should not.
