Barcelona finally confirmed the signing of Aubameyang on Wednesday, despite the 32-year-old having trained with his new team-mates on Tuesday after agreeing to a dramatic Deadline Day move to Spain from Arsenal.
The La Liga side has revealed he has an option to agree to his departure on June 30, 2023, with an £83.4m release clause in his contract.
Speaking in an interview on Barcelona's official Twitter feed, Aubameyang made it clear what his aims were, having signed a deal until 2025.
"I'm very proud, especially because my family is Spanish from my mother's side," he said. "I'm really proud and happy to be here.
My main goal is to help the team and give everything I can to bring the team back into the Champions League and stuff like that.
"I'm just happy to be here and I will try to give everything. It's amazing to have him (Xavi) as a coach, he's been a fantastic player as everyone knows and I'm sure as a coach he will bring us something that we will learn."
An Arsenal statement on Tuesday night confirmed Aubameyang's exit: "We wish Auba all the best for the next chapter in his career and thank him for his contribution to the club."
