The 37-year-old has led the Giallorossi to seven wins in as many games in Serie A, and Italy coach Cesare Prandelli has said he may look to call up the forward for next summer's World Cup finals in Brazil.
Totti, who retired from the national team shortly after the Azzurri's 2006 World Cup triumph in Germany, said to Gazzetta dello Sport: "For the time being I'm thinking only about Roma.
"In the spring I will see what my physical condition is and we will decide.
"But you can never say never."
Totti has scored nine goals in 58 appearances for Italy.
The Italians, who have two World Cup qualifying games coming up against Denmark and Armenia, have already booked their place in next year's tournament.
