How does it get to 9th?
From what I've reas, it's currently the top 5 go into the CL. The only way the league gets an extra CL place could be if Villa finish 5th and also win the Europa League (this wouldn't apply if Villa finished 4th and Liverpool finished 5th, for example, it'd only be top 5 in the CL for some odd reason). Also, in the scenario where the top 6 get CL, the EL place which 6th would have got doesn't drop down another place, it gets assigned to a different league (again, for some odd reason).
So essentially you're looking at top 5 in the CL (or potentially 6)
6th place in the EL (as long as Villa don't win the EL and finish 5th)
7th place in the EL (assuming City win the cup, otherwise it would be Chelsea, no matter where they finish)
8th place in the Conference league (as long as Chelsea don't win the cup)
I haven't seen any scenario where European qualification goes down to 9th?
