Things are not going his way at Old Trafford. The Chilean has struggled for form since moving to Manchester United from Arsenal last January. And the sources claim he could cut his stay short less than a year after making the switch.
He was left out of the staring lineup for the 3-1 defeat by Manchester City at the Etihad on Sunday.
And it is claimed that has pushed him even closer to the exit door.
Sanchez has fallen behind Anthony Martial in the United pecking order and has found first-team chances limited.
Even when he has played, the 29-year-old has struggled and scored just one goal in the entire campaign so far.
While moving in the summer is more likely at the moment, he could still try and go when the winter window opens if his situation does not improve.
Paris Saint-Germain have been linked with a move and appear to be the most likely option.
They are one of few teams who could afford to pay his reported £400,000-a-week wages – but they might have to wait until the end of the season, when they could be looking for a replacement for Neymar.
United manager Jose Mourinho is keen to bring in some reinforcements after a difficult start to the season and losing Sanchez would free up a huge chunk of money.
Mourinho is also reportedly looking to offload Eric Bailly and Marcos Rojo to help fund a spending spree.
He is desperate to bring in a new centre-back after missing out on one in the summer.
The club refused to sanction deals for Harry Maguire and Jerome Boateng as they did not believe either to be an upgrade on the players they already have.
Mourinho appears to disagree, however, and has struggled to find a solid centre-back pairing all term.
Bailly has not played since he was substituted in the 3-2 win at Newcastle at the beginning of October.
Victor Lindelof has started to cement a regular first-team place and Chris Smalling has been his regular partner in recent weeks.
However, Smalling is out of contact in the summer along with fellow centre-back Phil Jones. Can Sanchez be able to make friends and stay t the club? January is not that far,we will find out soon.
