Chelsea are pushing to sign Matthijs de Ligt from Juventus.
The Dutch centre-half is a top target for Thomas Tuchel's side this summer.
The Blues are seeking a replacement for Antonio Rudiger, who joined Real Madrid on a free transfer.
According to CBS journalist Ben Jacobs, Chelsea are hoping to secure De Ligt for a basic fee of £60-65 million.
However, Juventus are pushing to increase the fee, as there is interest from other teams in the ball-playing defender.
De Ligt has indicated his desire to leave Juventus for a side that can satisfy his ambitions.
