( CNN ) -- Inter Milan 's defense of their Serie A title may have taken a fatal blow with a 1-0 defeat at arch-rivals Juventus Sunday night . It left Leonardo 's men eight points adrift of city rivals AC Milan , who romped to a 4-0 home win over Parma 24 hours earlier , but they still have a game in hand . Alessandro Matri scored the winner for improving Juve in Turin after 30 minutes to improve their chances of claiming a Champions League spot . Frederik Sorensen 's cross was missed by Ivan Cordoba and Matri headed home from close in . It was only the second defeat for Inter under their new Brazilian coach who replaced Rafael Benitez and they offered little as an attacking threat . The best chance came eight minutes from the end as Samuel Eto ' o played a one-two with Wesley Sneijder but Gianluigi Buffon came out sharply to block the Cameroon star 's effort . Earlier , Lazio maintained their title bid with a 2-0 win at Brescia to stay third , seven points adrift . Goals from Alvaro Gonzalez after 18 minutes and Libor Kozak just before the hour mark secured three vital points for the capital side . Coach Edy Reja asked the fans to be patient after his side have slipped in recent weeks . `` We were top and then second and then we lost a few places but there are times throughout a long season in which it 's normal to have a bad spell , '' he told AFP . Udinese also kept up their pursuit of a European place with a 3-0 win at struggling Cesena . Antonio Di Natale scored a double allied to a strike by Gokhan Inler as they stay fifth . But Palermo saw their hopes nosedive with a shock 4-2 defeat at home to Fiorentina .
