Wenger is known for his carefulness when working in the transfer markets and again will take that approach despite Manchester City, Chelsea and Manchester United making some big-money signings so far this summer.
"Firstly, I must say that not being able to match the spending of the richest clubs does not mean that you can't compete with them on the pitch," Wenger told Time Out Hong Kong.
"When I first came to England, this question did not exist. Every club was run within its resources.
"The Chelsea and the Man City are new problems. But with this new financial environment, what has not changed at all is our policy that we will be as ambitious as ever and spend the money that we have available, if possible in an intelligent and wise way.
"We have always spent money because we are ambitious for top-class players and if you look at the history of our last 15 years, we have always had top-class players.
"It does not mean you can't win the title if you can't compete financially."
