Mohamed Salah missed Liverpool training on Tuesday due to a “sore throat”, according to Jurgen Klopp.
Salah was expected to start against Sevilla on Liverpool’s return to the Champions League after three years on Wednesday.
The Egyptian winger may yet feature, with Klopp taking the precaution to send him home from training on Tuesday.
“Most of them are looking really good apart from Clyney and Adam. Mo we sent home tonight,” Klopp said.
“He was in and the doctor told me he can train, but what would be best for him is if he doesn’t have to. He has a little bit of a sore throat.
“It shouldn’t be that serious so he can’t spread the virus if there is one.
“At this moment we expect him back tomorrow morning for normal training.”
