DESENZANO DEL GARDA - After a win and a draw, Inter's senior youth team lost 3-2 to Chievo in the third round of this season's Campionato Primavera.
Former Inter academy player Tonani took advantage of a defensive mistake to open the scoring, and Pinares curled a 25-yard shot into the top corner as the hosts took a 2-0 lead into the break.
After the restart Kirilov got between Benedetti and Faraoni to score Chievo's third, and Inter had a mountain to climb.
Bessa had two long-range efforts blocked by Silvestri but Inter eventually scored when Thiam tapped in after a mistake by the Chievo keeper.
It was third time lucky for Bessa, who beat Silvestri with an unstoppable free kick in the final stages, but time ran out before the Nerazzurri could grab an equaliser.
