text_A: At age 20, while still playing in the Italy under-21 side, Baresi was named in Italy's 22-man squad for the 1980 European Championship (along with his older brother Giuseppe) by manager Enzo Bearzot. The tournament was held on home soil and Italy finished fourth. However, unlike his brother, Franco Baresi did not play a single match in the tournament. Euro 1980 would be the only time the two brothers were on the Italy squad together at a major tournament. At age 22, Baresi was named in Italy's squad for the 1982 FIFA World Cup. The "Azzurri" won their third World Cup, defeating West Germany in the final, but Baresi, once again, was not selected to play a match throughout the tournament. Baresi was also a member of the Italy squad that took part in the 1984 Olympics. Italy finished in fourth place after a semi-final defeat to Brazil, and losing the bronze medal match to Yugoslavia. Baresi scored a goal against the United States during the group stage.
text_B: Would the announcers who were calling the play-by-play during the 1980 European Championship have found it sufficient to say "Baresi", without having to specify a first name as well, to avoid confusion?
YES.
