NewsLFC injury update: Jones, Alexander-Arnold, Alisson, Bajcetic, Endo, Jota and Robertson
Jones has made a return to full training after recovering from the injury he sustained away at Brentford in the middle of February, while Robertson sat out the win over Brighton & Hove Albion.
Elsewhere, Klopp reported Endo picked up a knock in last weekend's victory at Anfield, along with positive updates on Trent Alexander-Arnold, Alisson Becker, Stefan Bajcetic and Diogo Jota.
Speaking at his pre-match press conference on Wednesday, the boss said: "Curtis is in training, full training, and is in contention. Yeah, that's it pretty much.
"The other boys [are] doing well. Diogo and Trent are together in a group, which helps both, but [it] looks like from next week on they will be hopefully in parts of team training, and then we will see the rest.
"Ali is with the goalkeeper coaches, so I just see them through the fence, but that looks good as well. I think in his mind as well, next week parts of team training."
He later added: "Curtis is back, that doesn't mean he can play 90 minutes, he can play a few minutes."
Klopp continued: "He [Bajcetic] trains now fully with the U21s this week. That means we will take him in training next week to us and then we will see. Another one coming and that's super-important.
"Wataru, what a player, what a guy. He got a knock in the last game, so we have to see for tomorrow what we can do with him."
And when asked if Robertson would return, Klopp stated: "Yeah, and very important, by the way."
