Chelsea need pay him how much he want because looking with Rudiger quality as the best defender on primer league right now, he has success give Primer League and Champion League trophies for The Blues and should extended his contract have over this season. I think Chelsea have not any option with defender after Thiago Siva have over 35 years and Aplicueta have been 32 years old, need to get extended Rudiger contract excatly four or five years later.
Rudiger is a defender who can successfully fight for Chelsea for many years. I like him style.. One of the important generations of the German defense. And if they sign young, promising players like Çağlar Söyüncü or Demiral, Chelsea will not have a defense problem for many years. One of the best options for number 2 is Rudiger.
