Top trio Fluminense, Corinthians and Cruzeiro all drew their Campeonato Brasileiro matches.

Leaders Flu remain three clear at the summit after drawing 1-1 at Gremio Prudente. Rodriguinho's 34th-minute opener was cancelled out by Willian's equaliser with 18 minutes left.

Corinthians are their closest rivals but a 2-2 draw at home to Ceara saw them fail to close the gap.

Indeed, they were fortunate to take a point having trailed 2-0 to goals by Marcelo Nicacio and Magno. However, Paulinho levelled in the 70th minute before substitute Matias De Federico levelled eight minutes from time.

Third-placed Cruzeiro drew a blank in a goalless home draw with Atletico Paranaense.

Botafogo had to cling on for a point at home to Flamengo in a 1-1 draw in which both sides had a man sent off late on. Lucio Flavio had given them the lead but when Moura levelled in the 75th minute, Flamengo pursued a winner.

There was also a draw at Santos as they were tied 1-1 with Palmeiras. Patrick Lourenco equalised following Kleber's 20th-minute opener for the visitors.

Three second-half goals gave Internacional a 3-0 win over Guarani at home while Gremio also won 3-0, though they had to wait until the 90th minute for their second two.

Sao Paulo could only manage a goalless draw away to Avai as they suffered the dismissal of Richarlyson just before the break.

Atletico Mineiro twice came from behind to win 3-2 at Atletico Goianiense with substitute Ricardo Bueno hitting an injury-time winner.
