Alexis Sanchez, the Chile international has been linked with a move to Old Trafford, despite widespread reports initially indicating that switch was to Manchester City.
Sanchez comes to the end of his contract at Arsenal this summer, which means that if the Gunners do not sell him this month, they risk losing him for free come the end of the season.
According to The Telegraph, the 29-year-old has agreed a four-year deal with the Red Devils, and will pocket him £270,000 a week after tax.
The publication adds, though, that the transfer hinges on Henrikh Mkhitaryan and whether or not he will be included in a potential swap deal.
The Armenian international has struggled for regular game time under Jose Mourinho this season having started just 11 Premier League games for United.
