Juve and Napoli win, Roma in crisis

(ANSA) - Rome, September 24 - Cristiano Ronaldo scored to help Juventus clinch a 2-0 win in the closing stages at promoted Frosinone on Sunday and maintain their perfect record so far in Serie A this season.
    Second-placed Napoli also won, seeing off Torino 3-1 away, while AS Roma's poor form continued when they lost 2-0 at lowly Bologna.
    Juventus have 15 points from five games after Portugal star Ronaldo set them on their way by firing home from close range on the 81st minute.
    Federico Bernardeschi sealed the win deep into stoppage time.
    Napoli are three points behind Juve after Lorenzo Insigne scored twice in their win in Turin.
    Roma, who finished third last season and were expected to challenge for the title again this term, are 13th with five points after Sunday's shock loss to Bologna, who went into the game winless.
    Fiorentina are third thanks to a 3-0 home win over SPAL.
    Sassuolo, like Fiorentina, have 10 points after a 3-1 triumph over Empoli.
    Lazio are one point further back thanks to a 4-1 home win over Genoa.
    Inter climbed to a ninth with a 1-0 win at Sampdoria, but AC Milan are down in 12 after being held 2-2 by Atalanta at the San Siro.
