Arsene Wenger gave a public and final warning to Mathieu Flamini on Tuesday night over the midfielder cutting off the sleeves of his kit once again.
The Gunners put themselves in a strong position to qualify from their Champions League group with a straightforward victory over opponents Marseille at Emirates Stadium.
Flamini was, once again, impressive in front of the back four, but he also stood out from the rest of his Arsenal teammates with his differing sleeve length.
It was as straightforward a 2-0 victory that the Premier League leaders could have hoped for, but it now appears as though a row could be boiling over something bizarre as shirt sleeves.
Speaking to the press after the match, Wenger admitted he was not best pleased with Flamini's actions and sent his compatriot an unambiguous warning.
“I don't like that and he will not do that again,” he said.
“It is a club tradition and I was surprised. We don't want that.”
However, Flamini, who has been a revelation since joining on a free transfer in the summer, did not sound as if he was ready to heed the manager's warning.
"I've been playing for more than 10 years with short sleeves so what can I do?" he told reporters in the mixed zone after the game.
The 29-year-old clashed with Arsenal kit man Vic Akers for taking scissors to his kit before the loss to Manchester United earlier this month, going against a tradition at the club that the length of players' sleeves is chosen by the captain on the day.
It was a mostly pleasing evening for the Gunners, however, as a Jack Wilshere brace saw them top Group F with 12 points, a group described as the toughest drawn, and needing only to avoid a three-goal defeat in their final match away to Napoli.
