Yeah I think its all about being pragmatic.

If said player wants to leave, we have or have identified a replacement, and are get the money we want then all good.

As you said, there are lots example of great players rotting on benches.

Something that Olise didn't want at Chelsea presumably. Once fit again he'll want to carry on improving under the watchful eyes of Ray and Roy until he reaches the level that will likely make him one of the first choices at a big club if they want him and then he'll leave us (for a very nice fee).

It's a possibility but I think Liverpool might then want someone who is better on the defensive end to help out Alexander-Arnold. Salah is not that great on that front but, of course, his goals outweigh that as an issue

Newcastle seems a more likely alternative to me. Almiron isn't good enough for a Champions League team. Or PSG

Really? Since when has Salah been a central striker? Whenever I've seen him he's been playing wide right and cutting in to score his goals. Just because he's scored plenty of goals doesn't make him a central striker.

My prediction is he won’t go to Chelsea unless he wants to play next season in the Championship

He is played often as the main striker but whether you agree with that or not you are a moron if you believe Liverpool would look at Olise as a ready made replacement for Salah. And before you back track like so many on here do by saying ah yes but given time, coaching, blah, blah, he might get there in the end I'd say thats not what was suggested.
