AS Roma accused a former Aston Villa star of physically striking two of their youth players in a dressing room bust-up.
The incident is said to have occurred after the Primavera championship semi-final - an Italian youth football competition - between Roma and Fiorentina.
After the latter won 2-1 and booked their spot in the final, their youngsters were congratulated in the dressing room by one of their senior players.
Nicolo Zaniolo - who is currently on loan at Fiorentina from Galatasaray - reportedly commended the efforts of the club's youth team before heading to Roma's locker room, whom he used to play for.
