Club statement - National flags
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.
