Nicolas Jackson’s contract with Villarreal has a €35 million release clause which Chelsea have reportedly agreed to pay. However, the terms of an eight-year contract at Stamford Bridge are still being worked out. In January, the 22-year-old Senegalese striker almost joined Bournemouth for a transfer fee worth £22.5 million but he failed his medical due to a hamstring Injury. After recently acquiring Christopher Nkunku from German club RB Leipzig, Chelsea have identified Jackson as one of their key targets this summer to bolster their front line.
