Arsenal will wear their away kit in Sunday's north London derby for the first time in 38 years after their red-and-white home shirt was deemed to clash with Tottenham's colours.
The Gunners will don their black away strip at Tottenham Hotspur Stadium after referees' body Professional Game Match Officials Limited (PGMOL) said their home shirt "features too much white".
Arsenal also said wearing their home shirt with red shorts and socks was discussed but not agreed on.
As part of PGMOL's decision, Tottenham will also wear their away kit when they visit Emirates Stadium in the reverse fixture in January.
