The former Liverpool goalkeeper has been integral as Fluminense have moved six points clear of Atletico Mineiro at the top of the league.
“There’s still a long way to go,” Cavalieri told TV Globo after the clash. “Classicos are very difficult, you leave it all out there on the pitch. Now, we still have many difficult opponents ahead.
“The important thing is that we remain balanced. There is a good spirit in the group and that’s why we have managed to win difficult ties.”
