Arsenal fans are like Golden Retrievers. Extremely optimistic, with short-term memory, and require little more than the bare minimum to achieve maximum excitement. Whatever their faults as a fanbase, what you can't say is Arsenal fans do not get behind their players. In fact, the criticism of the club is that they might be too supportive of the players, as all it takes is a two-game winning streak for the fans to start believing they'll contend for a Premier League title. Does that overt optimism lead to a perpetual state of disappointment? It sure does. That's why there's a cliched saying among the Arsenal fanbase that it's the hope that kills you. However, just like with Golden Retrievers, despite nearly two decades of heartbreaking disappointment, Arsenal fans remain passionate supporters, ready to pounce on the next sliver of hope. Of the big clubs that have fallen from graces recently, how many can you say have remained as optimistic and supportive of the players as Arsenal fans? The answer is none, which is why this fanbase lands in fifth.
