"I will keep faith [with the current players] because we have worked hard for what we have now," said Wenger.
"We have money because we made money, and we made money because we made the right decisions.
"I believe a football team is not about buying and selling. It is about building, patience, working together and going through a growing process.
"Also, it is enjoyable now to see the team coming up slowly and see how well they can do."
Wenger is prepared to spend heavily but insists that his decision to invest in youngsters a few years ago has kept the need to go into the market to a minimum.
"I would have to be completely convinced that it is right and not stupid for the future of the club," he said.
"But I am in a position where I anticipated the years to come and I prepared for it."
