In May 2018, dear old Arsene Wenger finally stepped aside after 22 years at Arsenal.
Despite winning three Premier League titles and seven FA Cups, time had finally caught up with Mr. Wenger, and the Arsenal board effectively caved to fan pressure and shepherded aside Europe's longest-serving boss, albeit in the guise of a resignation.
It's safe to say that Wenger was not at the peak of his popularity upon his exit, with some quarters of the Arsenal fanbase disliking him so much that it had became their full-time job. Everything from a lack of summer signings, to failure to qualify for the Champions League, to Donald Trump winning the Presidency was all Arsene Wenger's fault.
