All of these are theories. None of these has an actual base. I know they are just possibilities and I think these things are possible to happen. But at the moment I do not see any reason why these are going to happen. Cost of all I do not think Liverpool will let go of Salah. He is really a valuable player for them to let go right now. And Liverpool is also not performing well. At this moment it is not going to be very wise to let go of a player who has been with the team for a long time.
Again, I understand what you are trying to say, and I also understand that all of these are possible. But I do not believe these are very probable.
Now it's really just a matter of seeing what happens next summer, whether Klopp will really leave Liverpool or not, even though this is very likely to happen.
As for some of the players that were brought, I think it's still too early because if we really look in the mirror from before when he went from Dortmund to Liverpool he didn't even bring a single Dortmund player there so indeed things like this are still not certain and this is as you said because it's just an assumption.
