The France international full-back says that he is focused on his club side at the moment but will think about his future in the summer after the World Cup in Brazil
The France international moved to the Premier League from Lille in January 2013 and has gone on to become a regular under Alan Pardew.
Debuchy is adamant that he remains focused on the Magpies, who are currently ninth in the Premier League, but will think about his future after the World Cup.

"After that, we don't know what the future holds. PSG is an immense club."
Debuchy has been linked previously with a move to PSG, prompting manager Pardew to insist in February that the full-back will not be following in the footsteps of Yohan Cabaye by swapping Tyneside for Paris in the summer.
"He is very happy at the club, he signed for four years and he is an important player who has done well and improved as he has gone along," the Englishman told reporters.
"We are looking to change and strengthen in a lot of positions next year but that won't be one of them."
Debuchy has made 25 Premier League appearances for Newcastle this season, scoring once in the 2-1 defeat to local rivals Sunderland in October.
