Liverpool have received a boost ahead of their Crystal Palace tie on Saturday, with news that Mohamed Salah is back in training.
Salah has been recovering from an ankle injury that saw him sit out of Egypt's Africa Cup of Nations qualifier matches against Kenya and Comoros, but joined the rest of the team in training on Friday.
Some of the players are however racing against time to be fit for the match, including the likes of Andy Robertson, Jordan Henderson, and Joe Gomez.
“Yesterday he trained. He trained the whole time since he was here, but only the things we wanted him to do," he said on Salah.
Klopp also provided an update of Virgil Van Dijk, saying he is fully-fit to feature at Selhurst Park.
“In the moment, yes, Virgil is 100 percent available,"
“But it’s the time of the year when players get out of the squad overnight, unfortunately, with some other things – getting sick or ill or whatever.
“From the others, I cannot say 100 percent, I don’t know 100 percent. Today is a very important session to judge that, especially with the players who came back late.
“Fabinho and Bobby and Ali played on Tuesday, Gini Wijnaldum played on Tuesday, so we have these players where we really need to have a look at how they react and what makes sense for them or not.
Liverpool will travel to face Roy Hodgson's Palace on Saturday evening hoping to continue with their perfect start to the new season.
They currently top the standings on 34 points, eight ahead of second-placed Leicester City.
