Sanchez has been benched in recent games after having failed to score this season and only scoring three times since joining United in January.
Wright suggested initially Sanchez was given time to adapt, but that now that time is up and the powers at United have grown frustrated with him.
Wright told BBC Radio 5 Live: “You look at Sanchez. He wasn’t under pressure to score instantly but by now he should have scored a lot more and contributed more.
“It does get to big players.”
After three-and-a-half years at Arsenal, Sanchez developed into one of the best players in England, scoring 80 goals in his 166 games for the Gunners.
He often carried Arsenal as they struggled for form in the latter years of Arsene Wenger’s reign at the club.
The Chilean seemed to embrace the pressure in these times, but after failing to recapture that form since moving to Man United in January, Wright believes the pressure is getting to Sanchez.
With his wages reported to be £500,000 a week before tax, going missing since joining United has represented an enormous financial hit for United, and one of the biggest in footballing history.
He was brought into Man United to deal with the pressure, and his track record with Arsenal, Barcelona before that, and even Udinese before that seemed to suggest it was a risk-free investment.
However, the reality is vastly different and Sanchez’s future at United is now almost inexplicably in doubt.
