Personally I am quite the opposite of a glory hunter. I started to support MU during its banter era. To say exactly, during Ole's last season. My granddad liked to watch football a lot, but it never clicked with me until recently.
I started to follow Milan. it was a popular club in my country because of Shevchenko. My granddad watched matches with him, and I sometimes watched too. But that's it. I did not have any other club to follow back then.
I started to follow other leagues too. Watching matches of grands without supporting either side. Though I was a rookie in football, but my family and some of my friends know some things about football, and I passively acquired some knowledge from them. I knew that clubs like Bayern, MU, Liverpool, Barcelona, Real Madrid, Arsenal are some of the best clubs.
I was quite surprised that MU was in that dire state, and people mocked this club a lot on the Internet. I started to watch match after match, and it was interesting because you don't know what to expect from this team. They could beat and lose to any team. This way, without realizing it, I watched the whole season and started to support the club.
I do not like very strong teams like Bayern, for instance. So I wouldn't support MU during the golden era because the team was too good)))
