Giuseppe Rossi scored his first European goal in more than two years, helping Fiorentina beat Pacos Ferreira 3-0 Thursday night in its Europa League opener.
The 26-year-old forward from New Jersey scored the hosts' final goal in the 76th minute on a left-footed shot from 12 yards, his fourth goal in five matches this season. Gonzalo Rodriguez scored the opening goal in the 30th minute when he headed in Rossi's corner kick.
Rossi tore the anterior cruciate ligament in his right knee playing for Villarreal against Real Madrid in October 2011 and had three operations before returning with Fiorentina on May 19. He had not scored in European play since getting two goals in a Champions League qualifier against Odense on Aug. 23, 2011.
