Cristiano Ronaldo's 400th goal in Europe's top five leagues was not enough to extend Juventus' perfect start in Serie A to nine games. Instead, Genoa hit back through Daniel Bessa for a 1-1 draw which allowed Napoli to cut the deficit at the top of Serie A to four points with a 3-0 win at Udinese.

Ronaldo reached the landmark in the 18th minute at the Allianz Stadium, finishing from close range as Genoa goalkeeper Ionut Radu made a mess of dealing with a corner. But Genoa had a better second half and Bessa's header made it 1-1 in the 67th minute. Napoli took advantage of Juve's slip with a routine win at the Dacia Arena.
