Arsenal centre-back Laurent Koscielny has warned the Gunners he will consider leaving if they fail to show ambition before the transfer window closes.

The French international was one of the side's better players in the latter half of last season. His performances helped Arsene Wenger's men to the final Champions League spot, ahead of Tottenham. He scored on the final day of the season, against Newcastle United at St James' Park, to ensure a fourth place finish.

"I want to have some titles. I hope the club will give itself the means. If that's not the case, I'll go take a look elsewhere," Koscielny told Eurosport France.

The 27-year-old has been linked to German and European champions Bayern Munich, with incoming boss Pep Guardiola an admirer of his ability. The Sun believes the Bavarians will bid for his services this summer. The former L'Orient player has however stressed that he is content to stay in north London, for now. And will likely only move outside the Premier League, if he does leave.

"I feel good at Arsenal, and if we're given the means to be able to rival big teams, of course I want to continue the adventure. If it's to be fighting each year like this season, mentally, it's hard," he explained.

"We're always under pressure and we know a single season without the Champions League at Arsenal is difficult. We'll have to see whether there are clubs who are interested. I don't just want to go anywhere. I want to discover a new championship," he concluded.

Wenger has been linked to Swansea City centre-back Ashley Williams, with a degree of uncertainty surrounding the future of Thomas Vermaelen. The Belgian lost his starting place to Koscielny and German international Per Mertesacker.

Vermaelen has been linked to Manchester United, Barcelona and Napoli. However, he has insisted he is willing to fight for his place in the squad and take whatever opportunities come his way.
