Arteta spent two seasons at the Etihad as the assistant manager to Pep Guardiola before making his move to Arsenal as the manager.
The Spaniard learnt a lot from the Man City boss that he already applies in his role as a manager.
One such lesson is not allowing a player to leave without signing his replacement.
The Gunners signed Matt Turner this summer that ultimately will pave the way for Bernd Leno’s departure.
McAvennie tells Football Insider: “You can’t just sell a player and not replace him. I don’t believe that you can do that.
“He’s learnt from [Pep] Guardiola. I don’t think he would allow anyone to leave if he thought they were going to be anywhere near his first team.
“So if he thinks people are going to be in his first team and he has to sell them, then he’ll need a replacement for them. It’s like for like they’ve got to sell and get somebody in, cheaper, that can maybe do the same job and maybe go on to be better than the boy that’s just walked out.
“So that’s what you’re hoping for.”
