Kaka was speaking after the shooting of football fan Gabriele Sandri (28), by a policeman during a scuffle between rival fans at the weekend that sparked violent clashes in several Italian cities, particularly Rome and Milan, leading to the suspension of matches.
The violence follows a match-fixing scandal which rocked the Serie A last season, and has left the 25-year-old, who is in the running for the World Footballer of the Year title, considering his future.
“It’s not the first time that this has happened,” said Kaka after training with the Brazilian team ahead of qualifiers for the 2010 World Cup on Tuesday night.
“Sport is a leisure which should be played with pleasure. When it’s not like that you have to find alternatives.”

Kaka, who is the highest earning footballer in Italy, added that it was not just up to the government to deal with the problem, but for players as well.
“I think that all players should act to find a solution as quickly as possible. This is something that goes beyond football. There is a social problem in the country and people are bringing this into the stadia.”
Italian police have made 25 arrests in the wake of the shooting, while football authorities suspended Second and Third Division matches; First Division matches are unaffected since none were scheduled this weekend.
At least 40 police required hospital treatment after the running battles in several cities on Sunday which newspapers dubbed the return of the ‘nightmare’ of hooliganism.
