Chelsea have resumed talks with Juventus over a potential swap deal involving Christian Pulisic plus cash for Matthijs de Ligt.
Juventus would prioritise a deal for the USA captain ahead of Chelsea striker Timo Werner who has also been discussed.
Thomas Tuchel is set to be backed heavily in the summer transfer market by new owner Todd Boehly, and he has made bringing in a new defender his priority.

Inter Milan’s Milan Skriniar and Sevilla defender Jules Kounde remain an options for Chelsea while they have also been offered the chance to sign Lazio midfielder Sergej Milinkovic-Savic.
