As a result, Mount has now been granted permission to discuss personal terms and undergo a medical ahead of a move to Old Trafford.
The Red Devils were determined to get their man after submitting three separate bids for the 24-year-old already this summer.
While their latest offer remained on the table, Man United had started pursuing other targets with Brighton star Moises Caicedo among the names on the list.
However, a deal for the England star now looks to be edging closer, something which has delighted former United star Dwight Yorke.
“I think it’s a fantastic buy if we get him and get him over the line,” Yorke told talkSPORT earlier this week.
“I really do like the look of him. I’ve watched him a few times and I think he’s got that X Factor.
“I think maybe a change will bring out the best in him and United will present a very good opportunity for him to do that.”
Chelsea had been keen to cash in on Mount due to the player having just one year left on his contract at Stamford Bridge.

Having progressed through the club’s youth academy in Cobham, Mount went on to make 195 appearances for the club, scoring 33 goals and providing 37 for his teammates.
As for United, they’re on the verge of making their first summer signing but Yorke believes they still need a new striker.
Asked who the Red Devils should be going for, Yorke said: “Well I think Harry Kane.
“Because we’ve got to close the gap on City… I think on the back of the success United had last season, they’ve got to close the gap and nail that no.9 spot.
“I think in the wide areas we’re fine. Mason Mount will give us a little bit more, maybe play as a no.10 occasionally, that’s a position he can influence a game a little bit more.
“We’ve got enough wide players, that’s not a concern. No.9… if we can’t get Harry Kane then we go for Victor Osimhen at Napoli but he’s untested, certainly in the Premier League.”
