De Silva impressed the Italian legend in his first few days on the training track as a Roma player this week.Like Totti, the young Aussie sees himself as a playmaker, potentially a future No10 for Roma.
"I like Danny, he is a great prospect," Totti, here in Melbourne for the first time, said.
"He has big potential and we've seen it over the two sessions he's done with us. He's a skilled player, he has a good nose for goal.
"But of course he's still young and he still has time to progress."
Roma signed the starlet in April 2014, in a deal that could net his former employers up to $2.5 million, depending on appearances and performances. Paul Okon, the former Lazio midfielder, stated he had "nothing to teach" De Silva as Australia U20 coach last year.
The former Perth Glory midfielder has made an instant impact in training here in Melbourne. It is the first time De Silva has joined up with the Roma squad after spending the last A-League season on-loan with Perth.
De Silva's coach Rudi Garcia also praised the 18 year old, but said he had a lot of maturing to do.
"We took a chance on Daniel because he is a very interesting player," he added.
"He is a very good prospect for the future, although he is young, and he needs to grow, and mature."
