The Red Devils have earmarked Mount as their priority target with manager Erik ten Hag aiming to add more goals and assists from the middle of the park next season.
Personal terms have already been agreed with the England international, but the Red Devils still have to settle on a transfer fee with the Blues to secure his services.
Speaking on Rio Ferdinand’s YouTube channel FIVE, David Ornstein has now revealed that Chelsea are expecting £70m up front for Mount with £10m in add-ons. However, United are hoping to negotiate a lower transfer package to their £55m valuation of him.
