The 31-year-old Brazilian defender has been the subject of much interest this summer as he seeks a move away from the San Siro, with the three clubs in the frame for his signature
Having expressed a desire to explore a new challenge, the Italian giants are willing to listen to offers as they look to shift on some of the more experienced members of their squad on high wages and the player's representative Roberto Calenda has named the clubs after the player.
"There is interest from Manchester City, Real Madrid and Chelsea in the player," Calenda told Calciomercato.
"There is no possibility that he goes to AC Milan or Juventus.
"He has worn the Nerazzurri shirt for six seasons and has too much respect for the fans to betray them in that manner.
"He could also yet remain at Inter."
With Chelsea recently completing a deal to sign Marseille right-back Cesar Azpilicueta, it remains to be seen whether they still remain in the race for the Brazilian.
However, Manchester City boss Roberto Mancini is known to be anxious to add some depth to his squad before the transfer window closes as he seeks to bolster his squad in a bid to retain the Premier League title this term.
