Claudio Ranieri's team are now level on 24 points with Inter Milan, who have a favored goal difference and one match in hand.

Two first-half goals made the difference, the first from defender Zoltan Grygera and a second from Amauri, his sixth league goal of the season.

There was a disappointing showing from Genoa's Diego Milito. The Argentine striker is the leading scorer with nine, but was unable to escape from Juventus and Italy defender Giorgio Chiellini.

Alessandro Del Piero flicked the ball over the defence and substitute Vincenzo Iaquinta used to his pace to race away from the defence and slot the ball past Rubinho for the home side's third.

The return to action of midfielder Mauro Camoranesi turned out to be effective as his cross made Sokratis Papastathopoulos turned the ball into his own net for the home team's fourth.
