Liverpool captain Henderson has recovered from the illness that ruled him out of the midweek Champions League win over Genk, while there is no issue for Van Dijk.
Both are therefore available for the top-of-the-table showdown this weekend.
Asked for a squad fitness update at his pre-match press conference, Klopp said: “Virg was for other reasons not here [on Thursday] but he is completely fine. Jordan is completely fine.
“Joel [Matip] is still out, like Shaq and like Clyney. That’s it, probably.”
