Former Arsenal manager Arsene Wenger admitted there was confusion as to who was in charge at the club during his final years there.
Wenger is a club legend at Arsenal, having managed the team for 22-years and won the Premier League on several occasions.
But his final years were marred by fan discontent and financial issues.
Wenger spoke about the end of his tenure and the subsequent years for Arsenal in an interview with French outlet Canal+.
"I don't know, it's not for me to judge. But what I see is that the club have started to reinvest a lot, and things started off badly," Wenger said.
"There was disunity. We no longer knew who was in charge and that's never good. Now they've created a unit, and now it's about making good technical decisions.
"You have to find some form of stability and balance. That will be the job of [Mikel] Arteta, who must find the balance between defending and attacking.
"Mikel Arteta does a good job, yes. The club has regained its values, but it is in the long term that we will see if the values will continue to be represented. Before, Arsenal was respected because we gave young people a chance."
Quizzed if the club asked him about Arteta after the sacking of Unai Emery, Wenger added: "No. When you leave a club, at the beginning you have to cut completely. But he called me and I wished him luck."
