The Magpies have tracked the right back for over two-years and are hoping to finally bring him to St James’ Park this summer but have struggled to agree a fee with Lille.
Owner Mike Ashley and Derek Llambias are refusing to pay over the odds for the 27-year-old leaving the deal at a frustrating standstill for manager Alan Pardew.
Having only signed youngsters Romain Amalfitano and Gael Bigirimana during the close-season the Magpies boss was hoping to springboard his transfer activity with the capture of Debuchy.
And Cabaye, who joined the Magpies from the Ligue 1 club in a £4.8 million deal last year, is confident his fellow countryman wants to make the switch to join him on Tyneside.
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.”
Champions League winners Chelsea and Inter Milan were also linked with Debuchy last month and could reignite their interest towards the end of the transfer window should they fail to land defensive targets of their own.
Pardew is also sweating over the future of striker Demba Ba and are said to be Newcastle bracing themselves for bids for the Senegal international with his £7.5 million release clause expiring on Tuesday.
