The big danger ahead for Arsenal is that after failing to take advantage of an undeniably golden opportunity to win the league this season, how long will they be able to keep their brightest talents? Saka, Ødegaard, Martinelli and Saliba have all come on leaps and bounds this season, but they're all at a good age for big sides in Europe to invest in. How long do they stay at Arsenal if City continue to dominate, as looks ominously likely?
Barcelona then City and their new wealth had a big hand in dismantling Wenger's late 2000s/early 2010s side. Now there's the looming shadow of Newcastle who are already challenging for the Champion's League spots, and haven't even begun to seriously flex their financial muscle yet.
