Arsenal returned all negative tests on Tuesday after players were tested as normal on Monday after Saturday’s match vs West Ham.
West Ham manager David Moyes has tested positive for coronavirus along with players Issa Diop and Josh Cullen.
West Ham only received the results shortly before the start of their Carabao Cup third-round match against Hull on Tuesday evening, for which Diop and Cullen had both initially been named in the starting line-up. A club statement said: “West Ham United can confirm that David Moyes, Issa Diop and Josh Cullen have returned positive tests for COVID-19.
“The club’s medical team were informed of the test results as the team were at London Stadium preparing for this evening’s Carabao Cup third-round tie against Hull City. The manager and both players immediately left the stadium and have returned home.
“All three, who are asymptomatic, will now follow Public Health England and Premier League guidelines and protocols.
“Everyone at West Ham United send their best wishes to David, Issa and Josh.
Moyes’ assistant Alan Irvine took charge of the match, which West Ham went on to win 5-1 as Sebastien Haller and Andriy Yarmolenko both scored twice, with Robert Snodgrass also on target.
