Antonio Conte's revamped Juventus outclassed Parma 4-1 in the first Serie A match in their new stadium but big-spending AS Roma boss Luis Enrique suffered an embarrassing loss on his league bow Sunday. Swiss right back Stephan Lichtsteiner got the party started at Juve's 41,000-seat arena, which still does not have an official name after a failure to find a sponsor, when he converted fellow new signing Andrea Pirlo's great dinked pass. Three excellent goals followed in the second half with Simone Pepe blasting home, new midfielder Arturo Vidal scoring spectacularly and ex-AC Milan playmaker Pirlo capping a wonderful debut by again expertly setting up Claudio Marchisio. The Serie A season got underway Friday when champion AC Milan drew 2-2 at home to Lazio. Napoli won 3-1 at Cesena Saturday. Roma, sixth last term, has spent millions on new players since being taken over by American investors but a 2-1 home defeat by Cagliari left new coach Luis Enrique scratching his head. Fiorentina beat local rival Bologna 2-0 in Florence. Atalanta reduced its six-point deduction for match-fixing last season by a point after a 2-2 draw at Genoa and Novara drew 2-2 at Chievo. Siena was held to a goalless draw at Catania.
