Rudiger left AS Roma in the summer of 2017 to join Chelsea. Since the transfer, Rudiger has established himself as a key defender in 159 official appearances for Chelsea. But last season, he suffered a setback at the beginning of the season. Under Lampard, Rudiger missed 15 of his 19 league games, making only 4 appearances.

New manager Thomas Tuchel, who took over after Lampard was sacked, took advantage of Rudiger. Rudiger played a key role in defense, appearing in 15 of the 19 league matches played since Tuchel took over. He also helped the team win the Champions League last season, appearing in all but two group stage matches.

This season, he has appeared in all seven league games and has been trusted by coach Tuchel, but he is having trouble negotiating a contract renewal with Chelsea. Rudiger's contract with Chelsea is set to expire at the end of the season. There are clubs concentrating on whether or not Rudiger will sign a contract. There are reports that Bayern Munich and Juventus are interested in signing Rudiger on a free agent next summer.

If Rudiger does not sign a new contract with Chelsea, he will be able to freely negotiate with other clubs from January and leave the club without a transfer fee next summer. Rudiger's choice is an important moment.
