Nasri has scored 12 goals in alle competitions for the Gunners this season.
He said in The Sun: “I think the title is definitely within our reach.
“For a start, United were supposed to play against Chelsea and I couldn’t see them winning that.
“I also think their game in hand isn’t a foregone conclusion because winning at Blackpool is not easy.
“I really think we have quality and we’ve got the maturity now that we were lacking before.
“We’ll see how we cope with all the matches over Christmas and we will get a clearer idea after that – but I’m full of confidence.”
