Despite the Gunners being without a trophy since the 2005 FA Cup, the French right-back believes that the North Londoners can achieve success next season, otherwise he wouldn't be negotiating a new deal.
"I truly believe we can be champions or else I wouldn't be playing football. I would have gone already. I truly believe we can succeed with the team we have," Sagna told gulfnews.com from Dubai.
"I strongly believe we have the quality to be the best in the Premier League.
"Look at the end of last season, when we got 26 points from a possible 30. Not a lot of teams can do this and this is what makes me believe we can beat anyone.
"What we managed last season can be done only by a true team with a great team spirit. I believe we can achieve a lot more."
