 He made his Italy U-21 debut at the age of 18 and racked up 32 appearances and 4 goals that season.Treviso extended his loan for one more year in 2007-2008 but even though he played 31 times and scoring 1 goal, Russotto failed to perform at a high level like the previous season and was used mainly as a sub.In the summer of 2008, he finally returned to Bellinzona, and then left out again on loan, this time to join Napoli in the Serie A, with an option for the Southern Italian side to make the move permanent.
