The France international has been repeatedly linked with a move abroad this summer, with PSG, Monaco, Bayern and Barcelona the main clubs reportedly in the running for his signature.
Koscielny has been most consistently linked with Barcelona, but Pep Guardiola is also understood to be very keen on the centre back as he takes over at Bayern.
The 27-year-old’s representative has denied that Barcelona have already made their move, but suggested a transfer for the £20m-rated centre-back looks likely to be on the cards.
"Laurent is part of a shortlist of two clubs," Courbis told Eurosport. "Bayern or Barca have not contacted the player to discuss a possible transfer but I know that (he) is part of a shortlist of three or four players from both clubs."
Koscielny reportedly caught the eye of Guardiola and Barcelona when Arsenal beat the Spanish champions 2-1 at the Emirates Stadium in a first-leg Champions League tie in February 2011.
Speaking to Eurosport earlier in June, Koscielny admitted he could leave Arsenal. "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.
"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. 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."
Arsene Wenger signed Koscielny from Lorient for an undisclosed fee in July 2010 and the defender is currently on a £75,000-a-week contract, with four years remaining, that he signed last summer.
