As much as I would like us (Arsenal) to win the FA Cup (again), to then be part of European football, dropping out might have a blessing of sorts...
Then, for 2021, we can solely focus on the Premiership and build/rebuild accordingly. However, I also understand some of the financial implications of not being part of a multitude of competitions.
It's a catch-22. Clubs need the extra money in order to build a better squad, but trying to compete in all competitions risks squandering the chance to win any one of them. Or playing the kids in the cups and getting roundly criticized.
