The No.11 was sent home from Melwood on Tuesday afternoon as a precaution due to illness, but is expected to be available to take part in the Champions League clash.
Klopp told his pre-match media briefing at Anfield: “Most of them are looking really good apart from Clyney and Adam.
“Mo, we sent him home tonight, that’s right. He was in; Mo said he can train, the doc said he could train. But then I asked the doc what would be best for him and he said [it would be] if he doesn’t have to train because he has a little bit of a sore throat.
“It should not be that serious, so we sent him home so he cannot spread the virus, if it is a virus.
“In this moment we expect him back tomorrow morning for normal training.”
