Tuttosport claim that the Spanish powerhouses are eyeing the Juventus stalwart as a potential alternative to the contract rebel.
The current Los Blancos central defender’s future is a source of speculation, with The Guardian stating that Manchester United are trying to pry the defender away from the Spaniards.
With Ramos’ contract ticking down and no new deal agreed, Rafa Benitez’s men are ready to turn their attention to the Italy international according to Tuttosport.
The 28-year-old has been a stalwart in the Bianconeri’s dominance in domestically over the last number of years and has amassed 47 caps for the Italian national team.
Benitez has seen Bonucci up close during his time coaching with Napoli and is reportedly a fan of the former Bari enforcer.
Bonucci has claimed four Serie A title and a Coppa Italia crown during his time in Turin and has formed a formidable central defensive pairing with international team-mate Giorgio Chiellini at the heart of Juve’s defence.
The Italian’s deal with his current employers expires in 2017, with the report claiming that Madrid are ready to launch a €30 million (£21m) offer for Bonucci.
