But Nainggolan has told Gazzetta World: "Everything is calm with (Roma's director of football) Sabatini. Will I stay at Roma? Yes, I'm going to remain here."
Youngster Ola Aina has signed a new four-year contract at Chelsea.
The 19-year-old defender put pen to paper after impressing in the youth ranks at Stamford Bridge.
Aina spent last season training with the first-team squad while featuring for the Under-21s side.
And having represented England at various youth levels too, Aina has now committed his immediate future to the club.
"Over the next four years I want to become a much better and established player," Aina said.
"I want to be able to play men’s football at a high level and hopefully break into Chelsea’s first team because that is the ultimate goal."
