Italian champions Juventus extended their unbeaten Serie A run to 44 games on Tuesday but dropped points for the first time this season as they drew 0-0 away at Fiorentina. ‘The Old Lady of Turin’ — who went through the whole of last season unbeaten — could be joined on 13 points should closest challengers Napoli beat third-placed Lazio on Wednesday. Juventus legendary goalkeeper Gianluigi Buffon said that both sides had been tired after playing at the weekend. “Fiorentina were good, they have a good coach and a playing system they believe in,” he said. “I would say that it is a good point we have got here, it is a good sign, as we clearly suffered. We allowed them three or four chances like all the teams who come here but we didn’t concede a goal.” Vincenzo Montella, the former Italian international striker and now coach of Fiorentina, said that he was frustrated at not taking all three points but was happy because it showed the team was making progress.
