Arsene Wenger’s side would usually wear a traditional home strip of red shirts, white shorts and white socks. But due to a clash with Manchester City's white home shorts, the EFL has confirmed that Arsenal will instead wear an almost entirely red ensemble at Wembley.
The Gunners also donned red shorts for their visit to West Brom on New Year’s Eve, understood to be the first time they had worn these kits since an away game against QPR on April 11, 1978. It could prove to be an inauspicious omen that Arsenal have won neither of those games.
Their light blue away kit would also clash with City, who are wearing their home attire in its entirety. In last season's FA Cup semi-final and a Premier League 2 game in August, City had worn blue shorts.
When Arsenal travelled to the Etihad in November they donned their black third strip, in which they were handed a 3-1 defeat.
Meanwhile Arsenal’s Premier League trip to Leicester, originally scheduled for Saturday, March 17, has been postponed due to the Foxes’ reaching the FA Cup quarter-finals.
