Born in Como, Lombardy, Bianchetti joined Inter from Corsico, a local team from the town of Corsico, the Province of Milan, Lombardy. He played for Inter in every ranks from U15, 16, 17 to the reserve in 2011. He also spent one season with Varese reserve in 2010–11 season as Inter did not had its own U18 team in Berretti League as wild card until 2011. Bianchetti won 2012 Campionato Nazionale Primavera and 2011–12 NextGen Series with the U19 team. Bianchetti also included in the first team occasionally but failed to play in competitive games. He was included in 2011–12 UEFA Champions League List B squad as no.44, a routine move for reserve players. In summer 2012 Lega Serie A changed the age limit of the reserve league to U19, and Inter's reserve transformed to a more age specific teams: U19 and U18. However, Bianchetti remained in Inter, just likes his predecessors Davide Faraoni and Samuele Longo who was one of the three age 20 "overage" player for Inter U19 reserve in 2010–11 season and 2011–12 season respectively. But on the other hand, Bianchetti was a real "overage" player as the regulation changed, thus Bianchetti did not had much chance for Inter U19 team in 2012–13 season, along with former captain Andrea Romanò, Daniel Bessa and Raffaele Di Gennaro, despite the latter two were forced to remain in Inter due to injury. Bianchetti did not play in 2012 Supercoppa Primavera, the conclusion of last season, where Inter also fielded overage players Alfred Duncan and Marko Livaja. Bianchetti remained in Inter's European squad, but promoted to List A, along with Romanò. However it was due to Inter did not had enough youth product to fill the 4 specific quota and the outcome was indifference.
