Real Madrid, Bayern Munich, Juventus and Paris Saint-Germain have reportedly all made contact with the entourage of Chelsea defender Antonio Rudiger.
The Germany international is yet to reach an agreement with the Blues over a new deal and is due to become a free agent at the end of the season.
Rudiger is now free to negotiate a pre-contract agreement with foreign clubs after entering the final six months of his deal, and the former Roma man is certainly not short of suitors.
According to Sky Sports News, Real, Bayern, PSG and Juve have all opened talks with Rudiger's camp over a pre-contract agreement, while Manchester United are also keeping a close eye on developments.
The news comes in spite of previous reports claiming that Real Madrid have dropped their interest in Rudiger, who is believed to have been left unhappy with Chelsea's renewal offers.
The 28-year-old has remained a staple of the Blues team under Thomas Tuchel this season despite his contract situation, starting 20 Premier League games and contributing two goals and two assists.
