I believe it's probably a couple million pounds. That's significant to you and me, but probably not most big clubs. I suppose it would probably make a difference to a club like Burnley.
It does not have any impact on UCL seeding - that should be based on their European performance historically.
146 vs 144 this year, from what I read.
But for the manager and players, it's pretty irrelevant between 2-4.
This season Liverpool waxed Hoffenheim in the 2 legged playoff to advance to the group stage. Didn’t slow them down much.
For at least next year, it's auto.
To be fair, the four spots are deserved.
Has to do with UEFA rankings for each country's league. Previously it was top 3 + playoff.
