Following their 1-0 win over Norwich, Manchester United have suffered a Covid-19 outbreak with club sources confirming a small number of players and staff have tested positive.
Subsequently, they were sent home before training on Sunday and those who were negative were only able to complete individual non-contact sessions.
The Canaries' previous opponents Tottenham Hotspur saw their Europa Conference League and Premier League fixtures postponed due to an outbreak at the North London club.
Earlier this week, Prime Minister Boris Johnson indicated that the nation would move to 'Plan B' following the increase in cases of the Omnicron variant of the virus which forced Premier League clubs to return to emergency measures.
