Chile global Sanchez was considered to be a coup when joining from Arsenal in January 2018, with interest from Manchester City fended off, but he has flopped badly and is considered to have put personal gain above professional ambition.
The squad are also apparently in the middle of a fall-out, with national newspapers reporting that the astronomical goal bonuses paid to Paul Pogba and Alexis Sanchez have caused a divide between the pair and the rest of the squad.
The Red Devils saw off city rivals Manchester City for the Chilean's signature last January.
"I don't want to blame all the players because I think that some players are here (at United) and they themselves don't even know why they are here".
But Evra believes that was purely down to the financial offerings of United and that Sanchez would have been better off moving to the Etihad.
After suffering abuse from fans after the final whistle on Sunday, Evra says he expects Paul Pogba to be one of a number of players to leave during the transfer window.
"He had Manchester City, they were offering less money but he was going to play better football than United - I'm sorry about that, but City play better football and [Pep] Guardiola will improve him". That's the United fans I know - they've just had enough.
Meanwhile, Real Madrid has made Paul Pogba their top target as the 25-year-old midfielder could be on the move next summer. Don't tell me he loved Manchester United when he was a kid.
"Alexis has a contract with us", he said.
"When we come back on July 1 we can have the next chat and that will be a nice little summer for me".
