#3 Arsene Wenger
While younger fans might be more accustomed to seeing an aging Arsene Wenger struggle to come to grips with a destabilizing Arsenal team, older fans know that the Frenchman is an absolute legend when it comes to football management.
When he was announced as Arsenal's manager in the summer of 1996, Wenger arrived with a non-existent reputation. The media were flabbergasted with the decision to appoint an unknown manager who had a funny accent, and a leading newspaper announced his arrival with the rather insulting headline: Arsene Who?
However, Wenger soon got the world talking about his exploits. He got a breath of international fresh air into a league that was dominated by sub-standard English managers.
Wenger's tactics as well as attention to players' diets and general well-being are regarded as revolutionary in football management. Under him, Arsenal became one of the most dominant teams in the land, regularly engaging Manchester United in enthralling title races.
The 'Invincible' campaign of 2003-04 will forever be carved in the annals of football history. But the arrival of billionaire owners massively altered the course of football in England.
Clubs like Manchester City and Chelsea rose with vast financial pull, and a number of factors ensured that Arsenal simply couldn't keep up. Still, Wenger deserves praise for keeping the club competitive despite a paucity of funds.
The latter years of his Arsenal tenure got to a head, with fans openly demanding for his sack. And after a series of unfavorable finishes, the Frenchman decided to step down in the summer of 2018.
In hindsight, his replacement Unai Emery has not fared too well either. While a return to the Emirates might be unlikely, Wenger remains eligible for one last stint in the dugout at the top level.
