Gianluigi Buffon
Antonioli never debuted for the senior side, but was selected in the Italy squad that finished second at Euro 2000, as third-choice goalkeeper, behind Gianluigi Buffon and Francesco Toldo. When Gianluigi Buffon, injured himself in an international friendly warm-up a few days before the beginning of the tournament, Antonioli became second-choice ahead of Buffon's replacement in the squad Christian Abbiati.
