Wenger told arsenal.com: "We have a team that can develop in the next four or five years.
"It may not be so long before we are on top again. If you ask me if we have the potential to achieve success this year then I say 'yes without a doubt'. It is important not to relate only success with money.
"I feel we make superstars. We have a feel for the game and the way we want to play football is linked to development and therefore you have to take your time a little bit. If you find an extra special player then OK.
"But I have not seen a number of what you might call world class players. World class prices maybe but not world class players."
