Totti is a household name amongst the Roma fans after having thus far spent his entire career at the club but the 36-year-old recently came under criticism for his sub-par performances.
Cafu, who played together with Totti for Roma from 1997-2003, has however jumped to to his former team-mate's defence, extolling the Italy international's qualities and highlighting his contributions to the club.
Speaking to reporters at a Champions League Trophy Tour in Rome, Cafu remarked "Totti is always strong, and as a Roman, fights for the team."
"He makes you feel great, and was a fantastic teammate.
"He has done a lot of brilliant things for Roma and for the Italian national team.
"I have always rooted for him."
The former Brazil international also backed current Roma head coach Zdeněk Zeman, who only started his second spell in charge of the club during the summer, to bring the Giallorossi to the top.
"I have some beautiful memories of Zeman," added Cafu, who played under Zeman during the coach's first stint at the club.
"We did not win the championship, but we played well and got some great results.
"I'm sure Zeman will find the right way to adapt this team to his style of play."
Roma are currently seventh in the Serie A table and will face Genoa in their next league fixture.
