Paulo Dybala proved he can thrive with Cristiano Ronaldo to score as Juventus remained perfect to defeat Bologna and stay top of Serie A. The Old Lady secured their sixth win in a row as they march towards what they hope will be an eighth straight title. Ronaldo failed to register after scoring three times in his last two league contests, but Juve still cruised at the Allianz Stadium. Blaise Matuidi's shot from a Dybala knockdown was parried into the path of the Argentinian, who smashed home the opener. And the Frenchman soon got his own goal in spectacular fashion.

And Matuidi, from a tight angle, sent the ball into the roof of the net to double the lead. Juve cruised from then on as Max Allegri's side march on with a key test awaiting this weekend. They host Napoli, who defeated them at the Allianz Stadium last season with a late Kalidou Koulibaly goal, which will add extra spice and motivation for the champions.
