Paris Saint-Germain and Bayern Munich have both been credited with an interest in Debuchy as they weigh up moves for the 28-year-old full-back in the summer.
Debuchy failed to commit his long-term future to Newcastle after being quizzed by French journalists over reported interest from PSG.
Mathieu Debuchy: "PSG? I am here until the end of the season and for next year, I do not know.
"Yohan Cabaye to leave Newcastle for PSG in January is a great loss for us so obviously I was sad but I'm happy for him because PSG is a great club.
"I had the opportunity to talk a little with Yohan Cabaye and it is clear he is really happy there."
Debuchy joined Newcastle from Lille in January 2013 and is under contract at St James' Park until 2018.
