Comparisons with Maicon are wide of the mark, according to World Cup winner, who praises the full-back's pace and precision and instead likens him to another great
The Italian side confirmed that they had signed Romulo on Tuesday from Cruzeiro for a fee believed to be around €2.5 million (£2.2m).
The marauding full-back has earned rave reviews of late and has been tipped to earn a call-up to the Brazilian national side.
One of Romulo's admirers is Dunga, who coached the national team between 2006 and 2010 and he highlighted the defender's strengths.
"He can reach the by-line with remarkable ease," Dunga told Corriere dello Sport.
"Romulo has tactical intelligence and above all, incredible precision in sending crosses to the middle of the box."
The 42-year-old was then keen to talk about how Romulo compares with other Brazilian right-backs, including former Roma player Cafu.
"In Brazil, many say he reminds them of Douglas Maicon and Cafu, but in my view the similarity is only really with Cafu," he added.
"Maicon is a different player, whereas Romulo has the same speed and change of pace as the former Roma right-back [Cafu]."
Romulo's switch to Serie A cuts short the player's loan move to Atletico Paranaense which was due to run until the end of the year.
