The Gunners are currently third in the standings, which looked unlikely at the start of the season after a slow start.
Wenger feels that his team can be challengers next term, and has confessed to wanting to sign a new striker, with Lukas Podolski in the pipeline.
“I just felt we had two weak periods in the season and you can only afford one. I knew when we were 17th (in August) that we cannot afford any weak periods anymore, so when that happened in January it was very difficult,” he is quoted as saying in The Daily Mail.
“If you look at the circumstances of the (second) blip it was down to the fact we had no full backs. Overall since October, since the team has gelled, we are not on too bad a run.
“Man City have had the opposite; they started in the way we are now. It is difficult for everyone to maintain that.
“Yes (we want Podolski), because we want to add some offensive strikers, because many times people say we rely too much on Van Persie, which is true, but if we can find world-class players, we will (challenge for the title),” he concluded.
