Paulo Dybala scored a hat-trick to extend Juventus' lead at the top of Serie A with a 4-2 win at battling Benevento on Saturday as Fiorentina, inspired after the tragic death of their captain, beat Roma 2-0. The Turin giants moved a step closer to a seventh straight Italian title, four days before they travel to Real Madrid needing to overturn a 3-0 deficit to reach the Champions League semi-finals. Juventus now lead second-placed Napoli, who travel to Chievo on Sunday, by seven points. But Roma's third position is under threat as they fell at home to Fiorentina -- whose captain Davide Astori died suddenly last month -- and who claimed a sixth straight win for the first time since the 1959-60 season. Malian forward Cheick Diabate scored a brace to twice drag Benevento back into the game but the rock-bottom side fell to their 26th defeat in 31 games. "Congratulations to the lads because today was important to win after the defeat against Real Madrid," said Juventus coach Massimiliano Allegri.
