Real Madrid want Rudiger to join Alaba, Militao and Nacho as the CBs to shore up their defense. The club is very optimistic of the signing. The problems are both PSG and Bayern also interested, and just like Madrid would have issues reaching his rumoured €12m net salary demand. The last offer from Chelsea was €8m/year and the player didn't like it at all. Tuchel has tried, unsuccessfully, to convince him.
