Arsenal manager Mikel Arteta hopes former captain Pierre-Emerick Aubameyang receives a "good reception" from Gunners fans if he returns to the Premier League from Barcelona.
Aubameyang was stripped of his captaincy last season before sealing a move to Barca, with further details of how the situation developed coming to light in Amazon's All Or Nothing documentary series.
In the latest episodes, released on Thursday, Arteta took strong action against Aubameyang after he returned late to training following a trip to Paris, setting in motion events that would lead to his departure.
The Amazon cameras also showed Arteta claimed to have record of numerous prior incidents of Aubameyang's indiscipline.
However, the Arsenal manager insisted on Friday he still has positive memories of the forward, who was the subject of much discussion as he emerges as a reported transfer target for rivals Chelsea.
"It's a long time since that happened. I cannot go back each time there is a series. I have made my comments on that," Arteta said of Aubameyang's exit.
"What has been done has to defend the club and put it in the best possible position.
"Auba is an exceptional player. He did so much for us. I hope he gets a good reception [if he comes back], because I think he deserves that."
Chelsea coach Thomas Tuchel worked with Aubameyang previously at Borussia Dortmund and said of claims of his "toxic influence" at Arsenal: "I experienced none of this.
"This has nothing to do with the situation at Arsenal, which I also will not comment about out of respect, because it's not on me to comment. I don't know what happened.
"In Dortmund, there was never an issue."
