How so? You really think they would offer him a contract extension if Klopp didn’t fancy him?
I think the point is that, from an accounting perspective, say a 4 year contract at £100k a week (a little less than what he is on today, but just a nive number) would cost the club £20.8m across the 4 years - the gamble is then on whether if we sell him, we'd recoup whatever % of that 20.8m we'd already sent on salary. So if we get £10m for him, say, as long as we sell him before 2025 we'd have made a small profit - and £10m for a midefielder gets you nothing these days.
If we lose Ox/Milner (for free), and don't sign Arthur, then also letting Keita go, whilst having 3 injury prone 30+ year olds as first choice (and at least 1 of them *more* injury prone than Naby), and then 2 extremely young in Curtis and Harvey, with nobody else is a risk and would need multiple, more expensive players to bulk the squad up - and it then becomes less a "does Klopp 100% want to keep him" vs "can we afford all the players Klopp does want, or do we have to keep Naby for, say, 1 year to give us the 2 transfer windows to refresh that area". Especially if we can get him to accept that small pay cut (or a larger one), it could influence Klopp in to keeping him around as, say, 6th choice for 1 more year
