The France midfielder has impressed for Toon so far this season.
"I don't want to build him up to much at this stage because he's still learning his trade," said Pardew. "There have been a couple of games this year where he's struggled - he needs to get a grip of the hurly-burly of the Premier League but if we can get him on the ball he's an outstanding player.
"There's no mystery why he's in the French national team. He has a gift of a pass - his vision is his real quality. He has that special intelligence. He showed that against Villa, where he and Cheik controlled the midfield, with help from Demba Ba, and that's something we didn't do very well last season."
