Robertson and Henderson sustained knocks during the 4-0 win over FC Barcelona on Tuesday night, with the former forced from the field at half-time.
Meanwhile, Salah sat out the contest altogether due to a head injury picked up at Newcastle United last Saturday, but Klopp is optimistic about the availability of the trio for this weekend.
Firmino, though, remains sidelined by a muscle strain.
The manager told his pre-Wolves press conference: “The famous three words of this week in the dressing room: ‘It’s only pain.’
“Very important for all the young lads to learn, I’ve said that already to the boys. Hendo said, ‘It’s only pain’, Robbo said, ‘It’s only pain’ - but it was real pain, wow!
“Unfortunately, Robbo could deal with the pain but only the rest of his body couldn’t because he couldn’t really activate the muscle anymore, some nerve hit or whatever.
“They should be fine [for Sunday].
“Bobby not [available] for the weekend, but we have time [before the Champions League final] and that should be enough.
“Mo looked good around the celebrations after the game, to be honest! The day before yesterday and yesterday he was running outside and will be part of training today.”
