Sigh

First of all, if we actually won the Europa league then 5 teams would go to the CL. We wouldn't be kicking anyone out unless Leicester also won the Champions League. There's a maximum of 5 spots so in that case the 4th place team would not get a CL spot.

Secondly, it's not as straightforward to win Europa as you're making it out to be. We can't just go in there and smash it, there are a ton of strong sides left in the competition: Zenit, Roma, Ajax, Bilbao, Shakhtar, Schalke, Fiorentina, Villareal. Then you have Tottenham, Monchengladbach, Sporting, Lyon and Basel dropping down from the the CL possibly.
