MANCHESTER UNITED star Alexis Sanchez’s move to the club has been a complete disaster – but his bank balance means he does not regret the move.

That is the opinion of Emmanuel Petit, who believes his former side have arrived at a perfect time to take on their Premier League rivals.

The Gunners are currently flying high in the league after their North London derby win over Tottenham at the weekend.

Pierre-Emerick Aubameyang scored a brace in a 4-2 win that saw them leapfrog their local rivals into the top four.

And they have a chance to solidify their Champions League hopes with another win over struggling United.

The Red Devils are eighth in the table and among their misfiring stars is Sanchez.

The Chilean is out until next year after sustaining a hamstring injury but his performances have been woeful this year after just one goal.

There have been reports of unease from the ex-Barcelona forward, but Petit believes he is happy where he is – because of his mega-money contract.

He told Paddy Power: “Alexis Sanchez is not the same player anymore. His move was a fiasco.

“Some people will say it’s because of Mourinho and the way he plays, and I understand that a manager can have a big impact tactically and when he picks the player, but we all know the exceptional talent of Sanchez.

“Mourinho did not give him poison that all of a sudden has taken away all of his qualities.

“For me, I’m thinking, what has happened to Alexis Sanchez since he signed for Manchester United? Where is he?

“I’m pretty sure he doesn’t regret the move because he is one of the best-paid player in the Premier League, so he must be happy with what is in the bank. On the pitch though, it’s been a disaster.”

The former France footballer went on to state that tonight’s match is ‘perfect’ for Emery.

He added: “Emery is 19 games unbeaten now. The first big test for him was against Spurs and now they face United.

“These two games have arrived at the perfect time for him. Arsenal need to know where they are as a team because they lost the first two big games early in the season.

“This will serve as a barometer for Arsenal now so this second one in succession is a massive game for the players and manager.
