Former AS Roma coach Zdenek Zeman has taken aim at AC Milan striker Mario Balotelli.
Zeman insists the jeers from Roma fans on the weekend were not racist.
"I am a man of Rome," he told RTL 102.5. "I have been here for 20 years and the people have always shown me love.
"I can only thank them - not only the fans of Roma, but also Lazio.
"The problem is not the colour of the skin, but the behaviour. If a player performs well, nothing happens.
"They did not whistle Balotelli because of his skin colour, but his attitude. He can be controversial at times."
