The 25-year-old told the Le Parisien newspaper that, "to sign for PSG would be my childhood dream."
He added that while he is still enjoying life on Tyneside, he would love to return to his home city and to play for the team he supported as a boy.
"I am under contract with Newcastle and I am very happy. First, I must save my club," said the winger, who has scored nine goals in 43 matches for the Magpies since joining in 2010, originally on a loan deal.
"Then, once my club is saved, you never know. Signing for PSG would be a childhood dream. If there is an offer, I will study it with interest. If there is a offer. The 'if' is important.
"PSG still lives in my heart. Playing there would be a wonderful gift."
