Manchester United have been forced to close their Carrington training ground for 24 hours because of the club's Covid-19 outbreak.
A number of players and members of staff are said to have returned positive lateral flow tests on Sunday.
The Red Devils are reportedly in talks with the Premier League about whether or not it is safe for Tuesday's Premier League clash with Brentford to go ahead.
A United statement read: 'Manchester United can confirm that following PCR test confirmation of yesterday’s (Sunday's) positive LFT Covid-19 cases among the first team staff and players, the decision has been taken to close down first team operations at the Carrington Training Complex for 24 hours, to minimise risk of any further infection.
