Former Arsenal midfielder Stewart Robson - at the club from 1981 to 1986 - branded Wenger "a dictator in many ways".
The French coach feels his considerable influence at Arsenal is positive.
"I feel responsible for the evolution of the club. When you've been here for 16 years, you're part of the history and the guy who is responsible for the values that the club wants to show in all aspects of daily life," Wenger said.
"If a manager stays at a club for 15 years, he is a 'memory' of the club. It gives you a kind of authority, because people respect the way you behave and the way you do things."
