Chelsea defender in constant contact with Real Madrid and PSG

Chelsea defender Antonio Rudiger has been in regular contact with Real Madrid and Paris Saint-Germain through his representative.

The German has entered the final four months of his Blues contract, and it appears he is eyeing a fresh challenge away from the club.

The Blues are willing to offer close to £140,000-a-week for a renewal, but Rudiger wants at least double to put pen-to-paper on a new deal.

According to Bild, there has been an impasse over the past few months, and this could pave the way for the defender's exit from the London giants.

Madrid and Les Parisiens are front-runners to sign him. Rudiger is expected to assess all options on the table before deciding on his next club.

Chelsea have not given up on keeping him beyond the summer, but it appears unlikely unless they are willing to come close to his demands.

Aside from Rudiger, Andreas Christensen and Cesar Azpilicueta could also leave the Blues on free transfers when their contracts expire on June 30.
