1. Same reason people wants a transfer even though we already got such an amazing team - it's exciting. Not Klopp leaving, of course, but rather the many different possibilities a new coach brings. I understand why picturing how Nagelsmann's Liverpool would look or how Pochettino's Liverpool would look would be fun for some.
2. It's somehow became a thing. Probably because he's Steven Gerrard and he will forever be linked with Liverpool. I don't think he will take over in 2024
if anyone finds imagining Pochettino at Liverpool fun - they probably need medical help
Ditto Nagelsmann, he’s still only the 2nd or even 3rd best coach RB Leipzig have had as of now
Anyway, I guess the point is that wishing away the years with Kloppo is a waste of time and energy and pointless at the moment, better to make the most of it rather than imagine possibilities after.
And he’s not going anywhere yet, although this virus probaly has changed a lot of football (and sports) peoples mindsets and thinking, and football has a bumpy path ahead as it is, and worst if theres another wave in the winter. Plenty to worry about from a bigger picture point of view than anything else!
