The 35-year-old former World Player of the Year celebrated his return to Brazilian football by helping his new side to a 1-0 victory over Gremio on Sunday
Former Brazil international Ronaldinho has set his sights on leading Fluminense to the Brazilian league title after making his official debut for the club on Sunday.
The two-time Fifa World Player of the Year joined the Rio club on a free transfer from Liga MX outfit Queretaro earlier this month and marked his return to the Brazilian top-flight by helping set up Fluminense's goal in a 1-0 win over Gremio.
And the 35-year-old is now focused on leading Flu’s charge to their first national title since 2012 after completing 90 minutes to help end the club's run of back-to-back league defeats.
“It is very important to debut with victory,” he said.
"It was beyond all my expectations. I didn't know if I would be able to manage the whole 90 minutes but I am very happy."
“The goal is to be champions, we know it will be hard but we will fight all the way.”
Ronaldinho played a major role in the game’s only goal, lofting a high pass to Wellington Paulista, who headed down for Marcos Junior to round the goalkeeper.
Gremio had been reduced to 10 men early in the second half when Wallace saw red.
Fluminense are third in the Brazilian Serie A, while fittingly for Ronaldinho the clash was against his first club Gremio.
"He added a lot," said Flu coach Enderson Moreira. "Ronaldinho will prove decisive in many games for us."
Ronaldinho is contracted to Fluminense until the end of 2016, when he will be 36.
The club's next fixture is a trip to Avai on August 8.
