3. Mamadou Sakho

Sakho moved from the French giants PSG to Liverpool in 2013. He was considered as the Eiffel Tower at PSG and since his move to Anfield, he has cemented his position at the back. The Frenchman has not been to his 100% in terms of fitness but in terms of commitment he has shown more than 100%. Liverpool have had the services of Jamie Carragher as a skipper playing at the center back position and Jurgen Klopp might want to consider another CB as a skipper. Sakho is 26 and if he maintains his fitness and his consistency, he can prove to be a valuable asset to Klopp and a possible skipper.
