Arsenal
manager Mikel Arteta has confirmed Pierre-Emerick Aubameyang was left
out of his squad for the game with Southampton because of a disciplinary
breach.

The 32-year-old was named on the bench for the Gunners' 2-1 defeat at
Everton last week but was left out of the squad altogether when the
team was announced on Saturday for the home clash with Saints.

Speaking before the game, Arteta confirmed the decision was taken was for disciplinary reasons. 

"Unfortunately, due to a disciplinary breach," he said when asked
about the player's absence. "There are non-negotiables we have set as a
club and I think we have been very consistent."

The Arsenal boss was asked how long Aubameyang could be out for, replying: "It starts today.

"Certainly it's not an easy situation and not a situation we want."

The Gabon international, who signed a new three-year contract at
Emirates Stadium in September last year, has scored just four times and
assisted once in 14 appearances in the Premier League this season,
averaging a goal every 259.8 minutes.
