Chelsea are set to complete new manager Mauricio Pochettino's first signing of the summer.
The Blues are close to sealing a deal for Nicolas Jackson from Villarreal with a medical now completed.
Per The Athletic, the 22-year-old will sign for a fee that is close to his release clause of 30 million.
Chelsea will pay a slightly higher sum, as they are making the payments in installments.
Jackson will likely be the main man up front for the Blues, who will sell Pierre-Emerick Aubameyang.
The Stamford Bridge club are in the process of a clearout, with Kai Havertz and Mason Mount also ready to leave.
