Lazio left-back Senad Lulic has sparked outrage in Italy with remarks he made about Roma defender Antonio Rudiger following Sunday's derby clash.
Luciano Spalletti's side claimed a 2-0 victory at the Stadio Olimpico thanks to second-half goals from Kevin Strootman and Radja Nainggolan.
Tempers flared in a typically feisty meeting of the capital clubs, with six players ending up with yellow cards and unused substitute Danilo Cataldi earning a straight red for his part in a fracas that took place in the dugout after Strootman's goal.
But Lulic's post-match comments about what he considered to be taunts from Rudiger have prompted a backlash, amid accusations of racism.
