Manchester United moved into the League Cup fourth round with a 3-0 win at Luton, while West Ham boss David Moyes and two of his players contracted the coronavirus ahead of their 5-1 victory against Hull as the pandemic caused chaos on Tuesday.
Moyes, Josh Cullen and Issa Diop all left the London Stadium after learning of the tests before kick-off and will self-isolate, with the trio said to be asymptomatic.
West Ham were not the only Premier League club affected by the virus as Tottenham’s tie at Leyton Orient was postponed after their fourth tier opponents suffered a Covid-19 outbreak.
