Debuchy has been linked with a move to Arsenal, who are seeking a new right-back following the departure of Bacary Sagna, and reports emerged on Saturday that a deal was in place after the player appeared to confirm the switch on Instagram.
However, Debuchy denied it was him who posted on the photo-sharing website but stated talks over a switch to the Emirates are ongoing: "It wasn't me who posted it on Instagram.
"Everyone is saying that, but nothing has been done. For the moment, we are discussing it. Arsenal are a great club. We'll see what happens."
