Terms on the swap deal involving Henrikh Mkhitaryan were finalised on Saturday morning and Sanchez has travelled north to Manchester ahead of completing a medical on Saturday evening and agreeing terms on a lucrative four-and-a-half-year contract worth around £450,000 a week.
United’s medical staff were with the team at Turf Moor on Saturday afternoon but are due to meet up with the 29-year-old new signing after the game.
Sportsmail revealed the player had said an emotional goodbye after his final United training session on Friday. ‘It was very tearful,’ said a source. ‘Henrikh has been a very popular figure here at United.
‘We know he isn’t too happy with the way this deal has been forced upon him.
‘He realises he has more chance of playing at Arsenal, but he would have preferred to leave on his own terms.’
United will pay a £20m transfer fee to Arsenal and £15m to the player’s agent Fernando Felicevich.
The Chilean forward will earn a £350,000-a-week wage plus an extra £100,000 a week for image rights over the course of a four-and-a-half-year contract.
He will also receive £7.5m a year for four years as a signing-on fee.
