Chelsea boss Frank Lampard has approved the sale of Toni Rudiger.
RMC says Lampard and Rudiger have reportedly both agreed that the 27-year-old leaving Chelsea is the “best solution”.
Paris Saint-Germain are interested in snapping him up during this transfer window.
The report suggests that PSG boss Thomas Tuchel and the defender “have exchanged many times on the telephone to discuss the possibility”.
Chelsea are keen to offload Rudiger permanently, but the French giants would prefer to sign him on loan this season.
