The France international has been linked with a move to the Liga champions but the defender's representative says no contact has been made regarding a summer switch
The former Lorient center back added fuel to the speculation linking him with a move away from the Emirates Stadium when he admitted he would leave the club if the Gunners did not start winning silverware.
Catalan daily newspaper Sport reported on Saturday that the Spanish champions had approached Arsene Wenger's side regarding a potential 14 million euro move for the France international.
But Koscielny's representative, Stephane Courbis, told Eurosport France that there has been "no contact" from Barcelona but claimed the 27-year-old center back is being targeted by Tito Vilanova's side, along with Champions League holder Bayern.
Courbis said: “I know that Laurent is part of a shortlist of three or four players for both clubs.”
It was revealed in May that Koscielny was the target of a 24 million euro swoop by Bayern, with new boss Pep Guardiola thought to be a big admirer of the defender.
Koscielny signed from Lorient for around 9.4 euros million in 2010, and has gone on to make 119 appearances for Arsenal in his three seasons at the club in all competitions, scoring 10 goals.
