Chelsea will reportedly have to pay £43million to land PSG defender Presnel Kimpembe this summer.
Thomas Tuchel is looking to bolster his back line this summer after losing Antonio Rudiger and Andreas Christensen last month.
There is also uncertainty concerning club captain Cesar Azpilicueta, who may be tempted to return to his homeland to join Barcelona.
The Blues could now turn their attention to Kimpembe to fix their defensive issues, but he will not come cheaply, with PSG valuing him at €50m (£43m), according to Foot Mercato.
