Cabaye, who made the same journey last summer in a £4.8million switch that proved one of the bargains of the transfer window, is confident Debuchy wants to come.
He told The Journal: "Mathieu has made a very difficult to decision to leave Lille, but he has made the decision. Now I hope Newcastle push for Mathieu and I want them to do the deal.
"I spoke with him two days ago and he told me he wants to come. I hope Derek (Llambias) and [owner] Mike Ashley will do the business now.
"He wants to play for Newcastle and I hope that he comes to Newcastle because, of course, he is my friend, but also a very good player for Newcastle."
