Juventus have become the latest team to make a free transfer offer for the 29-year-old Germany international, who is out of contract at Stamford Bridge at the end of the season.
Rudiger's representatives are in talks with Real Madrid and Paris Saint-Germain regarding a summer transfer away from the reigning world and European champions.
Chelsea's Premier League rivals are keeping tabs on Rudiger's position, with Manchester United interim manager Ralf Rangnick reportedly a long-time admirer.
Rudiger says he'll weigh all of his alternatives before making a choice in the summer, and that he's completely focused on Chelsea's remaining games.
Staying at Stamford Bridge has not been ruled out, but it is contingent on the ownership situation at Chelsea being resolved.
