The 24-year-old Chelsea star continues to be heavily linked with a move away from the side he joined when he was just four years old.
Man United's first offer of £40million was rejected by Chelsea, and a second bid of £50m was also knocked back, but United are confident a deal can be done.
A total package of £60m, made up of £55m plus £5m in add-ons, could be enough to land Mount.

"That was the only one I could get, and I was nineteen [years old] when I was there.
"I then went to Derby [on loan in 2018] and wore number eight and then I came back to Chelsea and all the good numbers were taken, but luckily I got that one back again."
Talisman Marcus Rashford occupies his favourite no.10 shirt right now.
Mount has made 195 first team appearances, scoring 33 times for the Blues to date.
