MILAN - Marco Mandelli's Giovanissimi Regionali followed up their 7-0 victory in the reverse fixture against Lumezzane by hitting the same opposition for six without conceding.
Barazzetta opened the scoring three minutes in, before Bertazzoli added a further two before the break.
Esposito then got in on the act in the second period, after replacing two-goal hero Bertazzoli. He added three of his own after the interval, including a great finish from outside the box for Inter's sixth.
