Kalidou Koulibaly is a player very familiar to Maurizio Sarri, as the Italian managed the player during his time with Napoli.
Koulibaly is a tall and imposing 6ft 5 centre back who would be sure to add much solidity to the Chelsea back-line. His ability goes beyond winning everything in the air, he is a composed ball-playing defender who would allow Chelsea to play out from the back with ease. Signing Koulibaly could see Stamford Bridge return to being the fortress it once was.
The 27-year-old would not come cheap. Transfermarkt value the defender at £60m.
Abramovich should look to tie up a deal for Koulibaly ASAP.
