It doesn't, it just means we could finish ANYWHERE outside of top 4. Maybe even relegation, but still win a cup.
Like I said, I voted for cup, as the whole experience of winning trophies is huge. I'm just saying I do understand why someone might want sustained top 4 and associated CL qualification. That doesn't make it ludicrous at all. Just a different view.
Again, doesn't work - you're bringing in factors that aren't in the question, like relegation and finishing 12th etc, that's obviously not going to happen. The question is winning the FA cup or finishing 4th, not winning the FA cup or having a rubbish league season.
