The on-loan Cagliari star denied his employers two points with a late equaliser that could have a big bearing on the title race
Radja Nainggolan admits he took a degree of satisfaction from scoring the goal that earned Cagliari a 1-1 draw at Inter after being "treated like a toy" by his parent club.
Inter loaned Nainggolan to Cagliari in August and the midfielder came back to haunt Antonio Conte's men with a 78th-minute strike in Sunday's Serie A clash.
The 31-year-old rifled a long-range shot past Samir Handanovic with the aid of a deflection off Alessandro Bastoni's heel to cancel out Lautaro Martinez's header.
