In 1936, Matta won the silver medal in the flyweight class after losing the final fight to Willy Kaiser, the German competitor. The American, Lou Laurie, won the bronze. In the final fight for the title, Kaiser attacked Matta from the outset, forcing the tempo at close quarters and keeping Matta at bay. When Matta tried to fight back Kaiser pushed the pace. Towards the end of the fight the Italian tired and Kaiser wrapped up a points decision and Germany's first ever boxing gold. The two men met again a year later in the European championship with the same results, although this time it was for the bronze medal. Matta and Lauria later turned professional with Matta going on to become the Italian champion. In 1937 Europe's boxing champions, including Matta, competed against the Golden Gloves in international fights.
