Alessandro del Piero scored in his last league appearance for Juventus as the newly crowned Serie A champion defeated Atalanta 3-1 Sunday to become only the second Italian side to win the title by going the whole season unbeaten. Del Piero signed off in style in front of the home fans as he doubled Juventus' lead in the 28th minute to cap a near 20-year career with the club. “I had tears in my eyes several times,” said Del Piero, who has yet to decide where he will play next season. It was also emotional at San Siro as AC Milan bid farewell to club stalwarts Alessandro Nesta, Gennaro Gattuso and Filippo Inzaghi as well as Mark van Bommel. Inzaghi scored to help Milan beat Novara 2-1. However, it was of little importance as Juventus was four points clear heading into the final game of the season and claimed its 28th league title last weekend after beating Cagliari 2-0 while AC Milan lost 4-2 to Inter Milan. “I don't know what to think,” Inzaghi said. “When I was injured at Turin, I thought I wouldn't play again, then today I played my 300th game, in front of my fans and scored a goal in my trademark style. Everything still hasn't sunk in ... maybe the fact that others are leaving saved me because otherwise I don't know how I would have reacted if I was on my own.” The city of Turin was in party mood with hundreds of thousands of fans gathered in the streets as Juventus celebrated its first title in nine years. Around 5,000 fans welcomed the team bus as it arrived at Juventus Stadium, decorated with three stars as the club still counts the two titles it was stripped of following the 2006 match-fixing scandal. Antonio Conte's team became only the third side ever to go the entire season without losing a game. Milan also won the title unbeaten in 1992. Perugia went the entire 1978-79 season without losing a game but didn't win the league. Elsewhere, Roma won 3-2 at Cesena in Luis Enrique's last match in charge. Simone Del Nero gave Cesena the lead but Bojan Krkic, Erik Lamela and Daniele De Rossi all scored for Roma before Mario Santana fired home a late consolation for the home side. Jonathan Biabiany scored to give Parma a 1-0 win over Bologna, while Fiorentina drew 0-0 at home to Cagliari. Del Piero was substituted in the 57th minute to a standing ovation as the players and staff of both teams joined in with the resounding applause for the club icon. The standing ovation and cheers continued even after Del Piero had left the field and he got back off the bench and walked around the pitch saluting the fans.
