Sky Sports pundit Gary Neville says securing a deal for Alexis Sanchez would be on a par with Manchester United signing Eric Cantona.
Reports in Italy and England suggest United are ready to hijack any Manchester City move for Sanchez.
The Chilean has less than six months to run on his current contract is reluctant to sign a new deal with Arsenal.
According to Red Devils legend Neville, Sanchez is just what his old side need.
“I think it would be an absolutely unbelievable signing,” said the pundit (via ESPN).
“If you look back at Man Utd’s big signings over the decades, Cantona came out of the hat, [Robin] Van Persie was a surprise, and they both helped United win titles. I think this could have a similar impact. He’s got the character to play at Old Trafford.
“It would be a coup, particularly for United fans, to have a player like Sanchez potentially come to them over City. It would be a strong statement.
“It’s pretty obvious he’s not going to stay at Arsenal. I think if United were going to buy him, £25 million would be an absolute snip.”
The Gunners could allow the 29 year-old to leave this month, swallowing their pride by picking up the phone to City to sell him for slightly less than half the £60m they agreed last summer.
Alternatively, they could hold on to the Chilean in the hope that he will return to his scintillating form of last season. The latter appears increasingly unlikely with many citing the Chilean to have mentally checked out back in September.
