I'd guess that Klopp is thinking along the lines of the below. Getting rid of Shaqiri and Origi and bringing in an attacker and midfielder to add more useful depth to the squad. Obviously no idea who he wants to bring in but I think the squad will end up looking something like the below on 1st September.
Not a "Home Grown Player". Maximum 17 players.
"Home Grown Players" over the age of 21.
Under-21 players. Do not not need to be registered in the 25 man squad.
Goalkeepers: Alisson, Kelleher, Adrian, Pitaluga
Defenders: van Dijk, Gomez, Matip, Konaté, R Williams, Davies, Trent, N Williams, Robertson, Tsimikas
Midfielders: Henderson, Fabinho, Thiago, Keita, Bissouma, Ox, Jones, Milner
Attackers: Firmino, Salah, Mane, Jota, Bowen, Minamino, Elliott
And out go Karius, Phillips, Woodburn, Ojo, Shaqiri, and Origi.
