Arsenal ace Theo Walcott broke ranks during victory over Hull City.
The Sun reports when you play for the Gunners you wear whatever sleeve length the captain wears.
But the England winger obviously stood his ground at The Emirates at Saturday lunchtime by searing short sleeves - thought to be the first time and Arsenal man had failed to stick with the club tradition.
Former skipper Frank McLintock is quoted in The Arsenal Shirt book as saying: "As the captain I never, ever made the decision on what sleeve length we would wear. It was discussed between the players in the dressing room and there were plenty of rows about it, but it was never just down to me."
