If that's the argument then book a Scandinavian hotel.
CAS overturning a decision because it violates the 'fair play' statute would open a can of worms that would drown CAS in litigation for years and years. It's also entirely subjective which means they don't need to do it.
The best argument in an appeal is always that someone made the original decision on a) the wrong facts, or b) the wrong interpretation of the facts. A 2 hour slam dunk on how Textor didn't have decisive control could be persuasive. Dribbling on about what Barcelona say to the press won't do anything.
If we do end up in the Conference League, all I hope for is that people - and especially the club - cheer the f*** up and get on with it.
Yes, it would've been great to take on Roma, Porto, perhaps Celtic and whoever else drops in. Not getting the Europa League sucks. Unfortunately, there's a chance that a week from now no-one outside of SE25 will give a toss about what happened.
At the minimum we will still have a - maybe to never happen again - chance to take on Anderlecht, Fiorentina, Besiktas and maybe even with a bit of luck win a European trophy and have back to back European campaigns.
If we don't make the most of that then all we're doing is spiting ourselves.
