Roma coach Rudi Garcia says last Sunday's game between Juventus and Roma will hurt Italian football.
The two teams led the Italian Serie A table before the game but questions have been asked after the final whistle following a number of referee mistakes, clashes between fans and Roma players and the high number of yellow and red cards shown during the match.
"I have a cool head [and] this game hurts Italian football," Garcia wrote on Twitter.
Controversy started in the 27th minute of the game when referee Gianluca Rocchi first awarded a free-kick to the hosts only to then change his mind and award a penalty after Maicon handled Andrea Pirlo's free-kick on the edge of the area.
And there was more controversy in the second half after midfielder Paul Pogba was tripped by Miralem Pjanic outside the penalty area but with the Italian referee again pointing to the spot.
The home win for Juventus means the Bianconeri lead the Serie A on 18 points with six wins and no defeats and only two goals conceded, both against Roma on Sunday.
