Mane, meanwhile, had surgery on a broken thumb picked up while playing for Senegal and Keita damaged his hamstring for Guinea - with scan results yet to be confirmed although it has been suggested he could be out for a fortnight.
"The medical staff of the Dutch national team spoke to the medical staff of Liverpool and made the decision that he was playing only the Germany game and then after back to Liverpool".
Salah and Van Dijk returned to Melwood, where their fitness was assessed by the club's medical staff, and look set to be fit to feature against Huddersfield, who sit 18th in the Premier League table.
However there was some good news for one key player; Virgil van Dijk has "no problems" according to the boss.
"It's too much in that competition: "Proper games, real opponents, it is better than having any friendlies", Klopp said on Friday ahead of English title-contenders Liverpool's match away to Huddersfield.
He said: "I have known Jurgen long enough, I know he loves to use smoke screens".
"Obviously he knows that he needs to try and do a little more than he is doing right now but he's giving his all and I'm not anxious at all".
"I have known him long enough and he likes to moan after the global break".
Huddersfield's form is a stark contrast as they seek a first win to potentially climb out of the relegation zone.
But Wagner is not convinced any of them will miss the match at 5.30pm on Saturday. We can watch the games but what they do in training you cannot know.
