Antonio Rudiger's agent is thought to be in talks with other clubs ahead of the Chelsea defender making a decision over whether to commit his future to the west Londoners, according to journalist Paul Brown.
As things stand, Rudiger is set to leave Stamford Bridge next year as his £100,000-per-week contract is due to expire at the end of June.
What's the latest news involving Rudiger?
Chelsea are desperate to tie Rudiger down to an extended deal, but their hopes of seeing the Germany international remain with the club beyond the end of the season worsened after he stalled over the offer of a £140,000-per-week contract in September.
Rudiger will be able to enter negotiations with overseas clubs when he enters the final six months of his agreement in January and, according to Spanish media outlet AS, Real Madrid are interested in securing his services.
The report suggests the Spanish giants could be in a position to offer Rudiger a deal which would double his current wage package as big-earners such as Gareth Bale, Isco and Marcelo are set to become free agents in the summer.
It has also been claimed that Antonio Conte could make a move to take the 28-year-old to Tottenham Hotspur following his appointment as head coach earlier this week.
According to Italian media outlet Corriere dello Sport, former Chelsea boss Jose Mourinho is monitoring Rudiger's situation and keen to welcome him back to Roma having left the Serie A side for Stamford Bridge in 2017.
The 48-cap Germany international's suitors also include Juventus and Bayern Munich, who are willing to make Rudiger one of the highest paid defenders in history with a £400,000-per-week contract.
What has Paul Brown said about Rudiger's future?
Brown has revealed that Rudiger is assessing his options as the expiry of his Chelsea agreement draws closer.
Although Rudiger is the subject of interest from numerous clubs, the journalist has insisted it is not a forgone conclusion that the centre-half will leave Stamford Bridge.
Brown told GIVEMESPORT: "It does sound like his agent's been talking to a lot of other clubs and there is a lot of interest there.

"I think Rudiger is going to test the market. It doesn't mean he's leaving, but I do think he wants to listen to what other people have to say."
Why are Chelsea desperate to keep Rudiger?
Although Rudiger failed to feature heavily during Frank Lampard's reign, he has become a key member of Chelsea's defence since Thomas Tuchel took charge in January.
Rudiger has yet to miss a single Champions League minute under Tuchel and has been a regular starter in the Premier League as well.
Tuchel is hopeful of seeing Rudiger remain at Stamford Bridge and has claimed the former Roma man has few reasons to leave.
