Lautaro Martinez earned praise from Inter boss Luciano Spalletti after netting a debut goal in a 3-0 friendly win over Swiss side Lugano on Saturday.
Signed from Racing Club this month, 20-year-old Martinez needed just 16 minutes to provide a glimpse of his promise by tucking away a rebound after his initial effort was saved.
The pair were among five new signings to feature for the Nerazzurri, with Stefan de Vrij, Matteo Politano and Kwadwo Asamoah also involved.
Martinez's half-time replacement, Yann Karamoh, sealed the visitors' victory with a second-half brace, suggesting he could improve on the four Serie A starts he managed in his first season at the club.
