"I remember the last time I was going down the tunnel, with my kids in my arms," Arteta recalled in an interview with the club's official website.
"I said to my wife, 'One day I will come back here as the manager'. It has come a little quicker than I expected but that was a dream.
"I've got more family now - I've got more kids! I've had more experiences but I had a very clear idea of what I wanted to do so, two years before my retirement, I started to do my coaching badges.
"I already had that feeling that I wanted to try this game over that line, and I am really happy where I am."
