Arsenal boss Arsene Wenger admits he has doubts about his team's title credentials.
Ahead of the trip to Manchester City, boss Wenger said: "In two weeks, we had a super high of beating Manchester United before a super low of losing to Aston Villa.
"This shows we have the potential but not the consistency.
"Let's win the next game, the next one and then we can speak about the championship.
"But let's face reality. We have to get our sleeves rolled up and show we can compete in any situation."
