The German coach hopes to obtain further reinforcements for his London team, and in particular in defense.
Chelsea manager Thomas Tuchel is targeting four new defensive signings.
According to the British daily Evening Standard, the German technician told his board that he wanted to recruit three more central defenders and a full-back this summer.
Tuchel must rebuild his defense
The former PSG coach has planned a reshuffle of the defense after the departures of Antonio Rudiger and Andreas Christensen. Marcos Alonso and Cesar Azpilicueta are also expected to leave and sign up for Barcelona. The Londoners therefore risk finding themselves out of defensive options.
