Emmanuel Petit believes Alexis Sanchez’s performances have been totally unacceptable at Manchester United given his pay rate

The Red Devils signed Sanchez in an exchange deal from Arsenal in January with Henrikh Mkhitaryan going the other way.

Sanchez signed a four-and-a-half-year contract with United that sees him earn £14m a year after tax.

But the Chilean forward has since failed to deliver what was promised at United after finding the net only four times in 30 appearances.

This has led to United manager Jose Mourinho dropping him at times this season with the club only eighth in the Premier League standings.

Now former Arsenal and Chelsea midfielder Petit has called on Sanchez to take responsibility instead of hiding away.

The French World Cup winner even suggested that Sanchez’s brother instead turns up to play at Old Trafford during match days.

“The manager is on the bench, so you need to show pride in your own performance when you are on the field and the first one who has gone into hiding at United is Alexis Sanchez,” Petit told Goal.

“He wanted to leave Arsenal because he was chasing the salary United could offer.

“Now he receives so much money and in nine months what has he done? Nothing. I have not seen him. I think they signed his brother.

“I understand that players believe they deserve certain financial rewards when they reach a certain level, but what we have seen from Sanchez at United has not been acceptable.”

The Frenchman also added that the United squad have let Mourinho down this season.

The Red Devils will host Arsenal at Old Trafford tonight in the Premier League with kick-off set for 21:00 (CET).
