Carrera unwittingly played a huge role in helping Milan go unbeaten in the 1991–92 Serie A season. During injury time of Juventus' home match against Milan on 15 September 1991, an innocent-looking cross from the right touchline hit Carrera's head, and the ball looped past a stranded Stefano Tacconi for the crucial equaliser. Milan would then go on to finish the season unbeaten, and embark on a record-breaking 58-match unbeaten streak.
