Chelsea appears willing to part ways with the 24-year-old Senegalese international following the summer acquisitions of João Pedro and Liam Delap, who are expected to be ahead of Jackson in the pecking order.
Following the arrival of Chelsea's new signings, Jackson will be looking to leave the club, as he is unsure of playing time under Enzo Maresca.
Man United wants Jackson
The Sun reports that Chelsea has slapped a hefty £100 million price tag on Jackson. This exorbitant fee could deter potential suitors unless Chelsea reconsiders its demands.
According to Sky Sports, via Sportal, Aston Villa and AC Milan are also interested in signing the Chelsea forward this summer.
Meanwhile, David Ornstein reports that Manchester United and Brentford remain far apart in their valuation of Bryan Mbeumo.
There has been little progress in recent weeks regarding a potential move for the Cameroonian international to Old Trafford. Despite this, Mbeumo remains United's top attacking target.
