PSG coach Laurent Blanc has made no secret of his desire to sign Cabaye, who last week returned to Tyneside for pre-season training.
Alan Pardew warned last week that it would take a huge bid to prise a player like Cabaye from the club.
However, wealthy PSG are in a position to meet Newcastle’s valuation, and there is a feeling that Cabaye’s departure is inevitable.
United are yet to sign a senior player, but there could be progress early this week, with director of football Joe Kinnear back from holiday.
