Roma skipper Totti can still improve - personal trainer
"Even today, I still don't know what his margins for improvement are, as he always surprises you with something different," Vito Scala told Corriere dello Sport.
"He has scored 16 goals this season, and is the most prolific striker of the year, despite coming off the back of two serious injuries.
"He is still aiming for the top. His objectives are to win many things with Roma."
