Antonio Rüdiger was a real front runner in defense, but he is one of four players whose contracts expire next summer.

Given the interest other clubs have shown in him, he also seems to be the hardest to tie , and in an exclusive interview with TalkChelsea, Fabrizio Romano named three of the teams “keeping an eye on his situation at Chelsea”.

🗣 “Bayern Munich, Real Madrid and PSG are all keeping an eye on their contract situation at #Chelsea.”

He pointed out that they were – for the time being – just watching but would likely all be looking for center-backs this summer, which gave Chelsea a tough bidding war to compete with on January 1st.
