Transfer market consultant believes Brazilian playmaker will remain at the Bernabeu as the Italian club do not have the financial clout to secure a deal this summer
The 29-year-old Brazilian playmaker has been linked with a return to Italy, and reports have suggested Roma would be interested in using De Rossi, a long-term Real Madrid target, to try and lure him to the Olimpico.
However, Bronzetti, who has a freight of associations in Madrid, has said the Italian side would face a losing battle in trying to bring Kaka back to Serie A.
He told Centro Suono Sport Roma: "A swap between Kaka and De Rossi? It's silly. They [Real Madrid] are not interested in him [De Rossi] as [Jose] Mourinho is covered in that role.
"Also, Kaka has four years on his deal and he is on €10 million [£8.9m] a season. I don't see how Roma could get him."
Madrid take on Real Zaragoza on Saturday at the Bernabeu.
