Goal understands that Antonio Conte has put the Belgian midfielder high on his wanted list as he looks set to take over at Stamford Bridge in the close season.
Reports also suggested that the 27-year-old, who has scored three goals in Serie A this season, had discussed the potential move to the Premier League with friends, but Nainggolan used his official Twitter account to deny the rumours.
Se non ho ancora parlato con nessun club, perché avrei dovuto parlarne con i miei amici? Forza Roma e forza Belgio per stasera!— Radja Nainggolan (@OfficialRadja) 29 March 2016
The Belgium international has appeared in 28 Serie A games this season for Luciano Spalletti's men and has featured in all but one of their Champions League outings.
