Mason Mount, a midfielder for Chelsea, will get a third offer from Manchester United of roughly £55 million.
The Old Trafford team will also issue a warning that if the Blues reject the offer, they will end talks with them.
The England international is considered to be worth £70 million to Chelsea.
Since Mount only has a year left on his contract and negotiations for an extension have failed, United believes that amount to be exorbitant.
Chelsea has already turned out United’s offers of up to £40 million and £50 million for Mount.
What will Mount contribute to Man United besides being “an exceptional player”?
Erik ten Hag, the manager of United, wants Mount to be his first acquisition of the summer as he aims to bolster his team following their qualification for the Champions League for the upcoming season.
Personal issues are not anticipated, and United is certain the player wants to join them at Old Trafford.
Mount, who has 195 appearances and 33 goals for Chelsea since his debut in 2019, missed the end of the domestic season due to injury, which resulted in the Blues finishing in 12th place, their lowest place in more than 25 years.
He played a key role in Chelsea’s 1-0 victory over Manchester City in the 2021 Champions League final. With the Blues, he also captured the Uefa Super Cup and Fifa Club World Cup.
The 24-year-old was a member of manager Gareth Southgate’s team for the 2022 World Cup in Qatar and has 36 caps for England, tallying five goals.
Mount graduated from Chelsea’s youth program before signing a loan deal with Vitesse in the Netherlands for the 2017–18 season. In 29 Eredivisie games, Mount scored nine goals.
The following season, he was loaned to Derby County, where he scored eight goals in 35 Championship games for the Rams, who lost to Aston Villa 2-1 in the play-off final.
Mount made his breakthrough under the recently hired Lampard when he returned to Chelsea in 2019, and he quickly established himself as a major member of the team.
Mauricio Pochettino, a former manager of Tottenham, was hired by Chelsea last month to replace interim manager Lampard, who had taken over when Graham Potter was fired.
Analysis: Chelsea won’t sell if valuation isn’t fulfilled.

Mason Mount’s predicament has been brewing for a while, but it now appears to be coming to a close.
Chelsea wants to keep Mount, but due to the uncertainty surrounding his contract, the lack of a deal, and Manchester United’s persistent pursuit, this can only go one way.
Players were specifically not to be allowed to enter the final two years of their contracts when Todd Boehly and the Clearlake group took over. They had been hurt by losing Antonio Rudiger to Real Madrid on a free transfer the season before, which left them with a lot of work to do in the transfer market.
Last year, Mount received two contract offers from Chelsea, and the money was on par with that of other well-known players at Stamford Bridge.
Chelsea even explored the option of extending Mount’s contract by a year, which would have increased his pay and given everyone more time to find a solution, but like the previous two proposals, it was rejected in an effort to try to obtain a resolution to the matter.
The fact that the club and the player have been unable to agree on wages is the fundamental problem with these negotiations.
United appears to be prepared to submit a second offer for Mount, but that offer has not yet been formally submitted, and the Blues say that they will not sell if their asking price is not fulfilled.
