Blanc has never hidden his admiration for a player he handed an international debut to when France manager back in 2010.
Cabaye is enjoying an excellent run of form and Newcastle boss Alan Pardew admitted he is getting 'nervous' about the prospect of losing his French playmaker.
Newcastle have long insisted they would not be selling any of their top names, including Cabaye, this month - but with some reports claiming that PSG could pay over £20million for the 28-year-old, that may be too much for the Magpies to resist.
Now Blanc has confirmed that PSG want a new midfielder, with injury ruling out Adrien Rabiot, and and the fact that Cabaye is eligible to play in this season's Champions League makes him an even more enticing prospect.
"It would be good to recruit a player in the heart of the game, and have an extra player in midfield," Blanc told Canal+ following PSG's 5-0 win over Nantes on Sunday.
"We need a player who has the same mentality as the others when they are on playing or on the bench. He must love to play.
"He must be technically good and be tough, and whether this player comes or does not come, there will be competition in all positions.
"I've been saying for a month and a half and the injury Adrien makes it more urgent to have an extra player in midfield.
When asked specifically about Cabaye, he refused to comment on claims that a deal was close but said: "I ask myself. I know the man.
"He has that character, but there are others. We are very happy with this team but with all competitions in which we are engaged, we must be aware that there will be issues and we already see that with Adrien Rabiot."
With Newcastle already pursuing Montpelier playmaker Remy Cabella, reports in France claim his arrival could offset a possible departure of Cabaye although Sky Sports understand the two deals are not linked.
Newcastle are also continuing talks with Borussia Monchengladbach over striker Luuk de Jong - who they hope to conclude in the coming week.
Blanc quiet about Cabaye? Really??? Cos all I can hear is a relentless tap-tap-tapping!!!- ninespuds
