Keita and Shaqiri had missed pre-season until now due to respective injuries, while Alisson, Firmino and Salah are returning late due to international commitments at the Copa America and Africa Cup of Nations.
They add to the squad that had travelled to Edinburgh for Sunday’s friendly against Napoli.
Kent’s future is unlikely to be at Liverpool next season after Klopp said they would sell the youngster.
Included in the squad is Yasser Larouci, plus fellow young left-back Adam Lewis. Forward Bobby Duncan also remains part of the group.

Klopp has described this week as “massively important” for the team, especially after some disappointing performances and results in pre-season so far.
“Of course you would like to get a bit more from training sessions than we got for example from yesterday [vs Napoli], admitted Klopp.
“We play Wednesday the game against Lyon but we have to see how we do that, we organised it months back when we thought ‘OK, they come back, they can maybe play 10, 20, 30 minutes or whatever’.
“We didn’t know in that moment it will be important for Shaq and Naby as well, but apart from that we have to prepare still the season and not only the game on Sunday, but of course the game on Sunday is the first proper game of the new season and so we try to be as good prepared as possible.”
