Manchester United are in discussions with the Premier League over postponing their fixture away to Brentford on Tuesday evening after being forced to shut down their training complex due to positive COVID-19 cases.

United said on Sunday that a "small number" of individuals among the first-team players and staff had returned positive lateral flow tests.

Those positive cases have now been confirmed by positive PCR tests, resulting in United shutting down their Carrington training complex for 24 hours "to minimize risk of any further infection".

In a statement on Monday afternoon, United added: "The club is in discussion with the Premier League whether it is safe for Tuesday's fixture against Brentford to continue, both from a COVID-19 infection and player preparation perspective."

"Team and staff travel to London will be deferred pending the result of that discussion."

The positive COVID-19 cases were first recorded at training on Sunday, where United's players were undergoing recovery sessions following Saturday's 1-0 win at Norwich.

Negative tests had been returned before the game at Carrow Road.
