Liverpool assistant coach Pep Lijnders is the latest member of staff isolating because of coronavirus as the club seeks to postpone Thursday’s Carabao Cup semi-final first leg at Arsenal.
Lijnders’ suspected positive test follows “a number of” suspected cases that saw Tuesday training cancelled.
The decision on whether the game is postponed is “still pending”.
Lijnders took charge for Sunday’s Premier League draw at Chelsea, with manager Jurgen Klopp already isolating.
Players Alisson, Joel Matip and Roberto Firmino missed that game too and three other staff members tested positive.
Liverpool – further stretched by the departure of Mohamed Salah, Sadio Mane and Naby Keita for the Africa Cup of Nations – cancelled a news conference due to be led by Lijnders on Wednesday.
The Reds applied for the postponement on Tuesday, issuing a statement saying the club wanted to give “as much notice as possible” to travelling fans for Thursday’s 19:45 GMT kick-off.
In a new statement on Wednesday, they said: “As a result of the outbreak and the suspension of preparations, as well as other illnesses and injuries recorded within the squad, the club submitted an application to the EFL for the postponement of Thursday’s tie with Arsenal, with the news of Lijnders’ positive result coming after the request was lodged.
“The outcome of this application is still pending.”
There were 94 new cases among Premier League players and staff from a total of 14,250 tests in the seven days up to and including January 2 – down from a record 103 cases over the previous seven days.
