i am not sure about about others,but i support arsensal way
before they got their 49 unbeaten match run.Before that i supported
no team (Not Liverpool or MU when they had their inspirational
Cantona)Started to support them since wenger came in and with
prudent policy bring in unproven players and polish them up to
result in a team that is good enough to challenge for honors,over
the years MU has being more dominant but that does not make me like
them more over arsenal.
As for those who call people Glory hunter,it is usually with a
reason.True fans usually do not boast about their achievements and
put other down.We see these "Chelsea Fans" coming in a shout how
good their team is and laugh at their defeated opponents, such
childish behavior is what result in specifically them being called
Glory hunter.People do not usually say immediately that all chelsea
fans are Glory hunter,but it is those who only come out to shout
how great their teams is,then what else do you call them other than
that since they only come out in moment of glory.
