Pierre-Emerick Aubameyang has confirmed he left Arsenal only because of a problem with manager Mikel Arteta.
Aubameyang was unveiled by Barcelona on Thursday having joined as a free transfer until 2025, after agreeing the mutual termination of his Arsenal contract.
The striker was halfway through a three-year deal that Arteta helped convince him to sign in September 2020.
But their relationship broke down beyond repair after Arteta froze Aubameyang out and stripped him of the captaincy last month following a breach of discipline.
