Diogo Jota will be a doubt for the Fulham game due to back issue.
The Portuguese forward scored a dramatic winner against Tottenham Hotspur on Sunday but will probably miss the Fulham game due to a back issue.
Klopp also explained both Firmino and Keita will miss the Wednesday clash even though they are back in full-team training.
Jota would be a big miss for the Reds if indeed that is the case. He has scored five goals in his last four league games.
Klopp told the media: “In our situation Bobby is out and Diogo struggles.
“He got, in the West Ham game, a knock in the back, a bruised rib, could not train before the [Tottenham] game but could play without an injection or whatever, but got another knock immediately when he came on.
“You might have seen the celebrations of Diogo, he was sitting down pretty slowly. He didn’t train since then so that is one that is a doubt… he is a doubt at least but I hope he can recover until tomorrow night.”
Klopp added: “Bobby [is] training, he looks good, not ready for the game, but is doing more and more so [we are] waiting for him in team training again. Pretty much the same for Naby.
