The former Spurs forward believes the Gunners star may have had his head turned by interest from Barcelona and Real Madrid
Dimitar Berbatov has said he would understand if Pierre-Emerick Aubameyang is unhappy at Arsenal, saying the striker's desire to win trophies could see him leave the Gunners.
Aubameyang's future is currently up in the air, with the 30-year-old's Arsenal contract set to expire at the end of the 2020-21 season.
Should the Gabon striker wish to depart, the Gunners may look to sell him in the next transfer window to avoid losing him on a free transfer.
