Rabiot has even been suspended by PSG for refusing to sign a new deal and has not played since December for the French side.
The 23-year-old has less than six months remaining on his contract at Parc des Princes, and it appears increasingly likely that the France worldwide will leave his current club on a free transfer.
The Daily Star is reporting that Spurs are keen to sign the 23-year-old Paris Saint-Germain midfielder this summer but are anxious that the could be beaten to his signature.
That's when Rabiot, 23, becomes a free agent.
Liverpool are also being tipped to bring in another midfielder at the end of the season as James Milner is coming towards the end of his career while Jordan Henderson has struggling with niggling injuries this campaign and Rabiot is reportedly on Jurgen Klopp's radar.
United chiefs could get the chance to watch Rabiot up close tonight as despite falling out of favour at PSG, the midfielder has been included in their travelling squad for tonight's Champions League clash at Old Trafford.
