Arturo Vidal nodded home the winner as Juventus secured a fourth straight Seria A title with four games to spare by beating Sampdoria 1-0 on Saturday. The Turin Bianconeri moved on 79 points from 34 games, 17 ahead of Lazio, who play Sunday at Atalanta. Samp, who were unbeaten at home, are fifth on 51 points and occupy the last of two Europa League berths, but could see city rivals Genoa and Fiorentina leapfrog them as they tackle third-place Roma and Cesena, respectively, Sunday. Vidal was undisturbed when he connected with a cross from Stephan Lichtsteiner on 32 minutes at Genoa's Luigi Ferraris, where Juve ran minor risks in the remainder of the game. Their league top striker Carlos Tevez stayed on 20 goals as he only forced a good save from Emiliano Viviano on 59, before substitute Gonzalo Bergessio missed twice for Samp and Alfred Duncan tried a long-range shot.
