Here's a slightly more cheery topic we can discuss: What made you support the team you currently support?
For me (not sure if I've told this tale before), I initially supported Arsenal for quite silly reasons.
My first encounter with football was the France 98 World Cup. I remember such highlights as Dennis Bergkamp's goal vs Argentina, a young Thierry Henry being tipped as the 'next big thing to watch', and a certain Davor Suker of Croatia whose name I thought was funny (I was 11 years old) but who ended up as tournament top scorer.
Following that, I had a copy of the Premier League sticker book, and Arsenal, being the first name in the book alphabetically, jumped out at me. So I literally picked the first team in the book as my favourite team.
I only casually followed Arsenal at that time, until the summer of 1999 when Arsenal signed, yes, Davor Suker. It was then that I felt, you know what, it's meant to be. Thierry Henry signed shortly after and that pretty much sealed the deal for me.
One of my most memorable first games I remember was that epic 3-2 turnaround at Chelsea where Kanu scored a hat-trick in the final 15 minutes. I literally jumped up and down on the sofa when that third goal went in during injury time.
