 He scored his first goal, against Scotland on his third appearance for the "Azzurri".He was included in the squad for the 1990 FIFA World Cup, where he appeared in four matches, wearing the number 10 shirt, including the third place playoff versus England which Italy won 2–1; in the final minutes of the match, he scored from a Roberto Baggio cross, but the goal was incorrectly ruled offside - though Baggio's opener was offside and the winning penalty was dubious.In the 1994 World Cup under Arrigo Sacchi, Berti was more established and played in every match on the way to and including the final; he notably started the play which led to Roberto Baggio's last-minute match winning goal in the quarter-finals, against Spain, with a trademark long pass, after winning back possession.
