The Brazilian defender, who is out injured currently, believes a win over Lazio this weekend can keep Giallorossi's title dreams alive
The Giallorossi are looking for a seventh successive win - not counting their suspended Serie A clash with Parma last weekend - as they meet fierce rivals Lazio at the Stadio Olimpico.
Dodo, 22, will not be involved due to a thigh injury but he believes a derby triumph could prove crucial as Roma attempt to record a domestic double.
"The derby win in the first stage of the season helped so much in giving confidence to the team. We hope that this return derby will help us in the same way," Dodo told reporters ahead of the derby clash.
"I will suffer to see the derby as a spectator, I'd love to play. I am focused on recovering as soon as possible so as to help the team."
The left-back also discussed Wednesday's dramatic Coppa Italia semi-final first leg, in which Gervinho's late goal sealed a 3-2 victory over Napoli, and Dodo thinks that Rudi Garcia's men are in the driving seat ahead of next week's second leg.
"The final goal gives us the advantage," the former Corinthians defender, who joined Roma in 2012, added.
"So far we have only lost one game all season so we have to be hopeful for the return leg."
Roma trail Serie A leaders Juve by nine points heading into the weekend's action, but have a game in hand on the Scudetto holders.
