3 at Palermo and Juventus opened Serie A with a sparkling 4-1 win over Parma Sunday as new managers Gian Piero Gasperini and Antonio Conte made contrasting debuts for the two Italian powerhouses. In Inter's first match since Samuel Eto'o transferred to Russian club Anzhi Makhachkala, the biggest problem for Gasperini was his porous three-man defense. Palermo captain Fabrizio Miccoli scored two key goals, including one in the 86th minute that broke a 2-2 deadlock, and South Americans Abel Hernandez and Mauricio Pinilla also found the target for the Sicilian squad. “We struggled with their counterattack and obviously those situations are not acceptable and must be improved,” Gasperini said. Diego Milito scored twice for Inter and newly signed Diego Forlan pulled one back for the visitors in second-half added time. New Juventus coach Antonio Conte, meanwhile, had little to worry about as newly signed midfielder Andrea Pirlo set up goals for Stephan Lichtsteiner and Claudio Marchisio. Simone Pepe and newly signed Chile international Arturo Vidal also found the target for Juventus as the Turin club played its first official match in its new stadium. Parma pulled one back with a penalty kick from Sebastian Giovinco in added time after Juventus defender Paolo De Ceglie was shown a red card. Elsewhere, it was: Catania 0, Siena 0; Chievo Verona 2, Novara 2; Fiorentina 2, Bologna 0; Genoa 2, Atalanta 2; Lecce 0, Udinese 2; and Roma 1, Cagliari 2.
