Nainggolan was aggrieved over Friday's defeat to the Bianconeri.
âIt went well that they played on âhomeâ turf! Because if we were at our house, it wouldâve been a different situationâ¦ Oh well!â wrote Nainggolan on his Twitter account.
âThe Juventini insult me after a game they won. How laughable!! But they couldnât hear their fans crying to the referee.
âThey won the game and still talk like thisâ¦ But how they cried and moaned when trailing.â
Juve supporters then confronted Nainggolan on Twitter and the Belgian international midfielder responded.
âYou donât even know the ball is round. :) You win and then offend people. You lose and itâs even worseâ¦â
Another fan suggested Nainggolan criticised Juventus, but would run to Turin if an offer arrived.
âYeah, thatâs why I said no in January. :) â
