The old firm is a joke. On one side, you'll have a large section of Celtic fans waving Ireland flags and wearing Ireland tops. On the other side you'll have Rangers fans waving union jacks, red hands of ulster flags, England flags and some will wear England tops. The thing is, 99% of the people involved dont really care about the politics, they just do it to wind each other up. My brothers a prime example.
Club statement - National flags at Emirates Stadium:
Some of our fans have been upset with the flying of certain flags denoting particular regions of the world
Arsenal as a club prides itself on being inclusive with respect to all nationalities, cultural and ethnic groups.
We have therefore decided that in order for all of our fans to enjoy their experience at Emirates Stadium, we are asking that only flags in support of Arsenal Football Club, without any national emblems, are displayed within the stadium.
We will be implementing this policy with immediate effect. Thank you for your assistance in this matter.
