Milan, Italy - Sulley Muntari's goal in the 73rd minute was enough to lift Inter Milan to a 1-0 win over Juventus at the San Siro on Saturday.
The result moves Inter four points clear of AC Milan at the top of the table with the Rossoneri visiting Torino on Sunday, while Juve falls six points back of Inter.
The best chance in a scoreless first half fell to Inter in the 33rd minute when Juve defender Nicola Legrottaglie turned the ball over in midfield, allowing Inter's Zlatan Ibrahimovic to carry the ball into the box on the left. However, the Swedish striker rolled his shot wide of the far post.
Ibrahimovic then set up Muntari inside the box for a shot from 12 yards but Juve goalkeeper Alex Manninger reacted well and tipped the ball around the post.
That duo did finally connect successfully in the 73rd minute with Ibrahimovic driving the ball towards the far post from the right and Muntari finishing the play into the empty net.
The visitors had a chance to equalize in the final 10 minutes from a corner kick when Alessandro Del Piero turned a header on goal from close range but Julio Cesar made a good reaction stop in the Inter net to snuff out the chance.
Fiorentina took over fourth place with a 4-2 win over Udinese as Riccardo Montolivo scored his first two goals of the season while Adrian Mutu and Alberto Gilardino also found the net for the Viola.
