Juventus coach Max Allegri was relieved to defeat Genoa - despite the 4-0 scoreline.
Paulo Dybala, Mario Mandzukic and Leonardo Bonucci struck for Juve.
Allegri said: “It wasn't easy, as Genoa had done really well against Lazio to draw 2-2 and had more motivation with the return of their Coach. It was a tough test, but we had the right mentality and approach.
“Genoa were man-marking us tonight and football is really tough if you don't move around. You need to shake markers off, create space and move the ball around too.
“We don't have the Scudetto yet, but we need eight points to be mathematically certain. Now we have a few days to prepare for another very difficult trip to Atalanta.
“We made a lot of changes today, but the important thing is that the result does not change."
