United is open to selling Sanchez during the transfer window in January, with the forward keen on joining PSG.
But The Independent UK is now reporting that PSG have no interest in signing the Chilean international, leaving him stuck in Manchester.
Sanchez joined the Red Devils in a player-swap deal that saw Henrikh Mkhitaryan join Arsenal.
The Chilean earns around £400,000-a-week at United but has just netted four goals and has been dropped by manager, Jose Mourinho in recent weeks.
Sanchez is reportedly fed up with life at Old Trafford and is seeking an exit less than one year into his lucrative contract.
Meanwhile, Spanish television show, El Chiringuito, had reported earlier this week that Sanchez had instructed his agent, Fernando Felicevich to find him a new club, and his representative has begun talks with Real Madrid.
The report also claimed that Felicevich is discussing the possibility of Sanchez making a move to the Santiago Bernabeu in the January transfer window.
Sanchez will hope to feature for United when they take on Crystal Palace on November 24 in the Premier League.
