Arsenal boss Mikel Arteta has rejected criticism from Chelsea striker Pierre-Emerick Aubameyang.
A video emerged in recent days of the Gabon forward slating his former manager Arteta's management skills.
Arteta was asked about Aubameyang's comments on the eve of Arsenal's Europa League clash with Bodo/Glimt.
"People are free to discuss what they want," he told reporters in Norway.
"I have never been in a better dressing room (than this season) - more enjoyable, more hard-working, a better relationship between staff and players and it is an absolute pleasure as a coach to be a part of this group."
