Defender Bacary Sagna is convinced Arsenal can win the Premier League again next season - and would have already quit if not.
Sagna, 30, is entering into the final season of his current deal at the Emirates Stadium, but is in talks over an extension.
The Gunners won eight of their final 10 Premier League games to overhaul Tottenham into fourth place, which secured another shot at the Champions League with a crucial two-legged qualifier in August.
Manager Arsene Wenger has been promised significant funds to build a squad this summer capable of mounting a long-overdue sustained title challenge, with Real Madrid striker Gonzalo Higuain and England forward Wayne Rooney linked as potential marquee signings.
France international Sagna, signed from Auxerre six years ago, has no doubts Arsenal can be contenders again in 2013-14, when they will look to end eight campaigns without silverware.
"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 www.gulfnews.com from Dubai, where he helped launch the new website www.BuyMyPlayer.com.
"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."
Sagna, though, warned his team-mates they must cut out the inconsistencies which saw them slump a low as 10th after losing at home to Swansea in December.
He added: "On some days we can switch off and lose to anyone and to avoid this, we need to take things game by game and stay focused from the beginning to the end.
"There are no major things that we ought to do to continue succeeding.
"I think we just have to stick around as a team, where each one helps out on the pitch, and stay consistent like we did in the second half of the season."
Sagna could become a free agent at the end of next season, and has been linked with a lucrative Bosman move to both Paris St Germain and Monaco.
However, the France defender indicated there was positive dialogue with Arsenal.
"We are still talking [about a new contract]. I never said I wanted to leave the club, but there are some journalists who want to speculate as I have just one year to go," Sagna added.
"The fact is that I am still at Arsenal and I am looking forward to playing next season.
"Arsenal made me grow as a player and as a man. People have been talking about me going back to France, but at the moment I am at Arsenal."
The Gunners will host Aston Villa in their opening fixture of the new Premier League campaign.
Arsenal will then face the first leg of their Champions League qualifier, for which they will be seeded, before heading to Fulham - with the crucial second leg of their European tie coming right before the north London derby with Spurs at the Emirates Stadium.
