Pierre Emerick-Aubameyang says Henrikh Mkhitaryan's transfer played a "big factor" in his decision to join Arsenal.
Aubameyang, 28, completed his club-record £56m move to the Emirates on Deadline Day, just over a week after Mkhitaryan arrived at Arsenal as part of a swap deal that took Alexis Sanchez to Manchester United.
Aubameyang admits the prospect of a reunion with his former Borussia Dortmund teammate played a key part in his decision to sign for Arsene Wenger's side.
"It's like [being reunited with] a brother, a good friend," Aubameyang told the Arsenal Weekly Podcast. "We played together in the past and I'm really happy to see him again.
"He called me a few times, he asked, 'Will you come or not?' I said, 'First you have to tell me if you sign or not'.
"He told me all was done and of course it was a big factor in coming here.
"We understand each other on and off the pitch, that's why it's easier on the pitch
"[The fans] have to be happy [to see us together], we will do our best of course, like we did in the past."
