IF the cherry of CL wasn't on offer, what would you celebrate more, winning the FA Cup or wining 4th place?
I would celebrate winning the FA Cup much more even with the CL for 4th place. This from a Spurs fan who has experience finishing 4th.
Awarding a CL place to the FA CUp winners is rewarding what sport is about, beating your opponent on the day, knocking them out.
