Speaking with SER Catalunya, Arteta was asked about almost leaving City - first to take the Arsenal job in 2018 and second about Newcastle's interest over the summer.
He said, "Yes, there have been some things, but the decision I have made is that I am very happy where I am, I feel very valued and fulfilled. And the road will continue here.
"Sometimes, I was about to leave, but I stopped myself.
"The first [time] was different, the second was mostly me. Firstly, that I am not in a hurry and I have not felt that I need to take the step.
"There are important conditions, especially in a first experience for me that are vital and eventually… I learned that these are essential to develop what you want, no matter how clear your vision is.
"And because I think we still have that space for improvement and that ambition to be able to do something we dream of, which is to win the Champions League. That work remains to be done.
"Winning the four domestic titles is something that nobody had done before and we did that with players who have a lot of development and improvement potential.
"And a group in which I am super comfortable.
"We have a staff environment where we are challenged daily but at the same time we have a very good human collective. And you are comfortable and have fun, and every day this good atmosphere helps a lot."
