The French defender has become a key man at St James’ Park since moving to the North East from Lille in early 2013, and was instrumental in keeping the club clear of relegation last season.
However, PSG boss Laurent Blanc is hopeful that he can lure him back Ligue 1 as a replacement for injured right-back Christophe Jallet.
The Parisians are hopeful of defending their status as their nation’s top club side while mounting a serious assault on the Champions League, and are concerned that the absence of their injured star could derail such ambitions.
Debuchy is seen as an adequate replacement, and a player that could potentially become one of their top names.
PSG are keen to explore an initial loan deal, but are likely to attempt to use this as a view to a full transfer at the end of the season.
Tottenham’s Kyle Walker is also on their radar, but Debuchy is believed to be a more realistic target given that added exposure to the French set-up ahead of the World Cup could guarantee him a spot in Les Bleus’ squad for the tournament.
