Arsenal have asked supporters not to bring national flags to matches at the Emirates Stadium.
The move comes after some fans have been upset at the waving of certain countries' colours.
"Arsenal as a club prides itself on being inclusive with respect to all nationalities, cultural and ethnic groups," read a club statement.
"We are asking that only Arsenal flags, without any national emblems, are displayed within the stadium."
The statement added: "We will be implementing this policy with immediate effect."
