flobaba After being garbage for close to a decade. If you recall even when we were steadily qualifying for champions league- when Wenger made top 4 like a trophy, there were grumblings and rumblings of dissatisfaction all about the place (it wasn’t enough for me).
So I think that was a reflection of the fact there were no outwards signs of progress (more signs that we were in stasis or in reality, a very slow decline). And that's the point for me, taking joy in the progress. Winning a domestic cup wouldn't necessarily represent progress (as much as I would enjoy the win).
Also, when we won multiple FA cups towards the end of Wenger's reign, Sanchez still wanted to leave...because we showed no signs of progressing in the league or in Europe.
