RIO DE JANEIRO, Oct. 21 (Xinhua) -- Ronaldinho was involved in all three goals as Atletico Mineiro closed the gap at the top of Brazil's Serie A championship with a 3-2 victory over Fluminense on Sunday.

After a goalless first half at Belo Horizonte's Estadio Independencia, Wellington Nem gave the visitors the lead from Fred's assist shortly after the restart.

Atletico's Jo equalized with a left-footed shot into the top corner following Ronaldinho's slide-rule pass before the former Manchester City forward struck again with a precise header in a move started by Ronaldinho.

Fred put the visitors back on level terms by sliding in from close range but Atletico restored its lead when the irrepressible Ronaldinho provided a lofted cross for Leonardo Silva, who nodded the ball past goalkeeper Diego Cavalieri.

The result takes Atletico Mineiro to 63 points, just six behind Fluminense with six matches remaining.

"This gives us belief that we can achieve our dream," Ronaldinho said after the match. "If they slip up again and we continue winning we are in with a chance."

Ronaldinho was unlucky not to score himself after referee Jailson Macedo de Freitas disallowed his 25m free-kick into the top corner for an infringement on Fluminense's wall.

In other matches on Sunday Ponte Preta beat Neymar's Santos 1-0 and Flamengo overcame Sao Paulo 1-0.
