Speaking on talkSPORT radio, transfer insider Alex Crook said: “We know Antonio Rudiger’s advisors have been in talks with the likes of Real Madrid and Paris Saint-Germain.
“I was told several weeks ago that it didn’t matter how much money Chelsea threw at him, his heart was set on a move to Real Madrid.
“We’ve seen numerous high profile examples — maybe Cristiano Ronaldo the highest of them all — of when a big club like Real Madrid come in for you it’s very difficult to keep them out of their clutches.”
Antonio Rudiger’s contract at Stamford Bridge expires at the end of the season and the center-back has already turned down several renewals offers from the Blues.
Chelsea will reportedly refuse to increase their £17 million-per-year offer and are set to start looking for potential replacements for the Germany international.
