The Italian international believes the former Giallorossi player and coach will be the correct choice to take the reins at the capital club
Montella has been heavily linked with a return to the club he served for 10 years after the the Spaniard was dismissed following a poor campaign, and De Rossi has encouraged the 37-year-old to make a comeback.
"I would be delighted if Montella returned," De Rossi told FIFA.com.
"I always thought he was a good coach and his experience in Catania has confirmed that."
But Catania is putting up a fight to retain Montella's services after Roma director Walter Sabatini made the team's interest official.
The Giallorossi is reportedly putting together a two-year contract worth 1.6 million euros per season to lure its man back to the Stadio Olimpico, with an option for a third year included.
