When choosing a club to support, when you’ve not been brain washed and indoctrinated into the cult from birth, you really have to do the research. I did a lot of looking into this guy named Herbert Chapman and the things he accomplished with the club. That was a factor. As well as the aesthetics of the style of play, which can be attributed to Wenger. When you are new to watching the sport, and you see a 10 man Arsenal team play a cheating paella eating Cuntalan side off the park in the CL final, that also has a big impact on any decision.
Seriously though Arsenal had by far the most cracking kit the year I started watching. That was the most important thing, had to look dank in my footie gear tho.
