The Belgium international midfielder saw his future called into question once again during the winter transfer window.
Antonio Conte has long been a fan of the combative 29-year-old and has been heavily linked with a move to take him to Stamford Bridge, while CSL outfit Beijing Guoan were reported to be plotting an approach in January.
Nainggolan has, however, seen the deadline in Europe pass with no deal done and reiterated that he remains fully committed to the Roma and prepared to discuss fresh terms in the Italian capital.
“I am very happy here and I don’t see any reasons why I would want to leave,” he told Sky Sport Italia.
“I am living well and I have everything that I need.
“I might sign here for life since I have rejected many teams in the past.
“If the team decides to sell me in the future then I can’t do much but at the moment, I am very happy to be here in Rome.”
Nainggolan first linked up with Roma in January 2014, with an initial loan switch from Cagliari turned into a permanent transfer later that year.
He has gone on to make 185 appearances for the club, netting 29 goals.
A 12-month extension was agreed to his contract in the summer of 2017, with that deal set to keep him at Stadio Olimpico until at least 2021.
