The Gunners moved up to second place in the Premier League table thanks to their 3-0 win over Manchester United before the international break.
That victory left Wenger’s men just two points behind leaders Manchester City after eight games, prompting some to claim that Arsenal could be genuine contenders for the title this season.
Chelsea, meanwhile, are 10 points off the lead after their miserable start to the season continued with their 3-1 loss to Southampton earlier this month.
However, Wenger insists that he is not paying attention to the fortunes of other teams and is only focused on steering Arsenal to victory.
Wenger told a news conference at Emirates Stadium on Thursday morning: “I don’t know [if Chelsea are title outsiders]. I don’t care too much about that. My worries are about my team and what we can do.
“We are two points behind the leaders and what all the other teams do is up to them. What I just want to say is mathematically you cannot rule anyone out at the moment.
“They [Chelsea] have some ground to make up. It is different to anybody out there at the moment, even Chelsea. Of course when you have many teams in front of you it is difficult to catch up but they have the quality.”
Arsenal travel to Watford on Saturday evening, while Chelsea take on Aston Villa at Stamford Bridge.
