Manchester United reported on Monday that they had confirmed cases of Covid-19 ,and had to shut down their Carrington training ground to help curb the spread of the virus.
They also said they were talking to the Premier League "given cancellation of training and disruption to the squad, and with the health of players and staff the priority" and that the team would not travel until a decision is made.
He said: "I think there needs to be a significant amount of Covid cases before the game can be cancelled, but to be fair I’m a little bit in doubt when it is enough.
“Whatever it is, I think it’s in the hands of the Premier League and they should make a decision so we all know what is best to do.
“If we can also make it very clear what the rules are to cancel a game, that would be good."
