Roma needed the result following a poor start to the season.
“This is a very important victory for me, but above all for the whole team that can give us a crucial boost for a more optimistic future,” the Brazilian said.
“It is the position I feel more comfortable in and where I feel I can help the team more. With the aid of all my teammates, thankfully I was able to score an important goal.
“The key thing, though, is that the spirit of the side was perfect tonight. We wanted this derby win.”
He added: “I dedicate this goal to all of my teammates, who are like family, and also to the Roma fans.”
