Speaking on Monday during a visit of the Italian Paralympic delegation preparing to take part in the September 7th-18th Rio Games, Raggi said: "In September, after the summer, we'll tell Gianni Malago (co-president of the candidacy committee) what we think about Rome 2024.
"Let's first think about abandoned municipal installations and sport in schools," she added in comments reported by La Gazzetta dello Sport.
"It's starting with these installations that we must begin to rebuild sport. The Olympic Games are a great sporting moment, but one is not born Olympic, one becomes it."
Raggi was elected mayor in June, continually repeating in her campaign that the Games were not a priority for the Italian capital.
Rome is one of four candidates to host the Olympics in 2024 along with Paris, Budapest and Los Angeles. The quartet must submit the second part of their candidacy by October 7th.
