Their unbeaten start to the new campaign has led some observers to tip them as title contenders, but with a tricky fixture away at Manchester City on Sunday, Podolski says such talk is premature.
"We have only played four matches. It's [too early] to speak about the championship," he told Arsenal Player. "When you win a match, you are not a champion. When you lose a match, you are not a champion.
"It's very important [to keep playing well]. We have had some strong matches, but Man City played in Madrid and now against us - it's a tough week."
