Manchester United's most recent match which was against Brentford has been postponed. And they have a home match in two days against Brighton now. Mata and Matic are still ill now but the condition of the rest of Manchester United's squad seems to be normal. And I don't see anyone who is ill in Brighton's squad. If it stays the same until the match, I don't expect the match to be postponed. Manchester United will have a tough match but they can continue winning I think.
