Real Madrid, Paris Saint-Germain, Bayern Munich and Juventus have all made contacts with Antonio Rudiger’s representatives over a pre-contract agreement this month.
Rudiger’s Chelsea contract expires at the end of the season and he is now free to discuss a deal with foreign clubs ahead of a free transfer in the summer.
Chelsea wants to extend Rudiger’s contract and staying at Stamford Bridge has not been ruled out by the German international and his representatives.

The initial offer made by Chelsea for a contract extension was rejected by Rudiger and his representatives.
Rudiger is understood to remain committed to Chelsea for the remainder of his contract and focused on helping Thomas Tuchel’s side achieve their objectives, despite the uncertainty surrounding his future.
Manchester United interim manager, Ralf Rangnick, is also an admirer of Rudiger and he is close to Rudiger’s brother.
