Angry fans protested on the terraces and fought with police, while on Saturday around 250 Cruzeiro fans gathered in front of the team’s training ground to remonstrate with the players over results.
Mancini himself was fired by Ceara earlier this month, having been head coach there for five months. He now becomes the fourth manager this year for the relegation threatened club.
The club said on their website: “Mancini’s contract is until December. Emerson Avila will return to his previous job as technical co-ordinator.”
The decision came one day after a 3-0 home defeat by Brazilian championship leaders Vasco da Gama.
It was the 30th coaching change of the year among Brazil’s 20 first division clubs.
Cruzeiro began the year with Cuca in charge and he was replaced by former South Africa coach Joel Santana, who lasted three months.
