Manchester City have confirmed three more cases of the coronavirus, with goalkeeper Scott Carson, teenage midfielder Cole Palmer and a member of staff testing positive, Reuters reports.

“Manchester City FC can confirm that Scott Carson, Cole Palmer and one member of staff have tested positive for Covid-19,” the club said in a statement.

“Both personnel will now observe a period of self-isolation in accordance with Premier League and UK government protocol on quarantine.”

With first-choice goalkeeper Ederson one of the other players already isolating, Carson's positive test leaves City short of options for Wednesday's League Cup semi-final against Manchester United.
