Arsenal midfielder Mathieu Flamini has been banned from cutting the sleeves of his match shirts after doing so for a second time.

The Frenchman disobeyed the club's unwritten rule that all players should wear the same length sleeve as the captain by cutting his for last night's 2-0 win over Marseille in the Champions League.

When manager Arsene Wenger was asked to comment on it in his pre-match press conference, the Frenchman said: "I don't like that, it won't happen again."

Flamini did the same thing for the Gunners' 1-0 defeat to Manchester United on November 10.
