Magpies boss Alan Pardew has been on Debuchy’s tail for much of the summer and now looks poised to capture the France international after the two clubs came to an agreement.
The 26-year-old represented his country at Euro 2012 last month and also courted interest from Chelsea but now looks set to join fellow Frenchman Yohan Cabaye at St James’ Park.
His arrival could spell the end of Danny Simpson’s three-year spell on Tyneside after Reading were linked with a move for the right back who has a year remaining on his contract.
The 25-year-old has so far resisted signing a new deal due to the club not meeting his wage demands and could be sold to the newly promoted Royals in order to balance the books.
However the signing of Debuchy will represent a significant step in the right direction for Pardew in the transfer market after he missed out on Twente striker Luuk De Jong.
The 50-year-old has only managed to bring Romain Amalfitano from Reims and 18-year-old Gaël Bigirimana from Coventry City in what has been an underwhelming close season compared to last year.
Pardew admits Newcastle are possibly paying the price for their astounding business in the last summer window with clubs now aware of the way in which they operate.
He said: “Possibly, possibly, but the market dictates, really.
“It’s all well and good a club asking for an unrealistic figure, but the bottom line is that the price will be the price.
“You have to be patient in the market sometimes to get the man that you want. Nine times out of 10, the two owners get together and it all becomes very realistic.
“But up until that point, it gets a bit cloudy.”
