Manchester United handed an ultimatum in their transfer pursuit of Chelsea's Mason Mount.

The attacking midfielder is out of contract in a year, which means the Blues are looking to sell him this summer.

Mount has not agreed to a new deal at Stamford Bridge, while British media reports state he prefers a move to United.

Fabrizio Romano claims the Red Devils want the deal, while Mount does as well.

However, Chelsea do not want to negotiate and are seeking £70 million for a player out of contract in a year.

Romano said: “There is still no official bid from Man United to Chelsea. United know, at the moment, that Chelsea don't want to negotiate.

“Chelsea are not open at the moment to sit at a table and negotiate for Mason Mount.

“80 million (euros) at least, or nothing. This is the position of Chelsea for Mount.

“At the moment United don't want to pay that money. They want to pay way less than this.

“This is why there is a big gap between United and Chelsea. Let's see if Chelsea open negotiations in the next days.

“We know the player is keen on the move, so Mount will be prepared to say 'yes' to this opportunity to leave Chelsea and go to United.

“But again it's Chelsea creating the biggest issue. They are not accepting this possibility."
