Former Roma centre-back Leandro Castan has revealed Radja Nainggolan used to leave the club dressing room to smoke with the assistant manager.
Nainggolan, now with Serie A side Cagliari on loan from Inter, played alongside Castan at Roma from 2013 to 2016 before the Brazilian went on a series of loans before signing permanently with Vasco da Gama in 2018.
While immediately impressed by what Nainggolan could do on the pitch, Castan revealed the Belgium star would do what he wanted off it, regardless of what other people thought.
