Also, Liverpool wouldn't be guaranteed qualification if they win the champions league but finish 5th

Then again, the FA would probably get UEFA to have them in and move Everton to the UEFA Cup, should they finish 4th.
It would be harsh on whoever misses out really, if Everton finish 4th then they thoroughly deserve a champions league place, but if Liverpool win it then they should be in as holders really. I can't see them winning it anyway, but still..
