"I have had many moments when I have felt down because we have lost a big game, but I never ever had any doubts that I did not have the support of the club," Wenger told Arsenal TV Online.
"As for all the rest, well you are ready to suffer and work very hard for your success.
"This job is difficult without the support of everyone at the club. Without that you have no chance."
Wenger admits he has made Arsenal more cosmopolitan during his decade in charge.
However, the Frenchman feels it has proved a positive evolution, the club having now moved from Highbury to the impressive, new 60,000-seater Emirates Stadium.
"We have always tried to respect the values of the club. It was like that when I arrived, but afterwards we have tried to adapt to the modern game. That means there is more of a foreign influx and we have been open to outside influences," Wenger reflected.
"We have become more international and more sophisticated in our approach to the game, but we try to keep that way of believing in our strength to integrate the sophisticated approach that you need for the modern game."
