The last time the two clubs met, Totti was sent off for attacking former Inter striker Mario Balotelli.
Sneijder said: “Totti is a legend. He is the symbol of the Giallorossi.
“Even in Holland, when you talk about Roma, the first name to come up is Totti's. He is considered an extraordinary champion all over the world.”
Sneijder was also asked who he believes Inter's main title rival will be this season.
