Antonio Rudiger's agent reportedly met with Barcelona on Wednesday to discuss the possibility of moving to Camp Nou on a free transfer this summer.
The Germany international's contract with Chelsea is due to expire at the end of June, and it appears increasingly likely that he will be leaving Stamford Bridge ahead of next season.
Manchester United, Juventus, Real Madrid and Paris Saint-Germain continue to be credited with an interest in the centre-back, who has again been a vital player for the Blues this term.
However, according to Sky Sports News, Barcelona are now showing an interest, with Rudiger's agent meeting with the Catalan outfit's officials on Wednesday.
The report claims that Sahr Senesie, who is also the defender's half-brother, met with Barcelona sporting director Mateu Alemany and deputy Jordi Cruyff.
The 29-year-old is currently unable to sign a new deal with Chelsea due to the sanctions placed on owner Roman Abramovich.
Rudiger has scored three times and registered four assists in 42 appearances for Thomas Tuchel's side during the 2021-22 campaign.
