In 2005, newly promoted Serie A club Treviso acquired his services on loan but made him play with the "Primavera" side all season, where he formed a valid striking partnership with Italian youth international Robert Acquafresca. Russotto did later make his debut in Serie A that season, at the age of 17, and completed the season with 4 first team appearances. Famed magazine World Soccer even inserted Russotto on the list of the top 50 young players in the world, as one of only two Italians (the other being Lorenzo De Silvestri).
