France midfielder Samir Nasri insists the best is yet to come from Arsenal`s young side following their 2-1 win over Manchester United last weekend.
The Gunners, missing a host of first-team regulars through injury and suspension, overcame United thanks to a Nasri double.
The 21-year-old, who will be rested for the Carling Cup fourth-round clash against Wigan, firmly believes the league title is within reach after passing a huge test of character.
"Maybe we don't have the experience of Liverpool, United or Chelsea but we showed how mature we have become after last season and after the last few weeks," said Nasri. "We showed we have a quality, technically, to win games like this one. Saturday was the greatest game of my career so far because of the rivalry between the two clubs and the performance.
"It is important to keep it going now. Mentally, we made a point by beating United. We know that the title could be achieved by the games against the big four and on Saturday we showed we can do it. With all the players coming back from injury we are going to get better and better.
"We are back in it but we always thought we were in it anyway even before that game. We know our qualities, our strengths. We know what we can do and we can definitely achieve the title this season."
