The Frenchman has come under intense scrutiny over the past couple of months, most noticably after the Gunners' quarter-final defeat by Bradford City in the Capital One Cup.
But Wenger maintains that he has an easier job now than he did in the glory-laden years when he first took over.
“I am never satisfied. I just try to do my best and I believe I would like to go away and think I have done that," Wenger told The Mirror.
“I have been under the most criticism in the last seven years. But I feel as a manager it was more difficult in the first years I was here.
“What I believe, as well, is that the club has grown since I arrived. When you compare where the club is today from then, you can see that.
“When I arrived, the club was at Highbury with no training ground and only 80 employees.
“Today we have nearly 500 employees, play in a great stadium and have a big training centre.
“And we are a club known throughout the world. We have been consistent at the top level.”
Arsenal are closing in on eight years without a trophy but Wenger insists that he has left a legacy at the Emirates Stadium which is bigger than any single triumph.
He added: “Our legacy will be our style of play. A way to see football. A way to see the development of the game and overall a happy attitude towards the game.”
