AC Milan are being held to a 0-0 draw at the San Siro by Lazio, despite having a number of chances.
Milan started brightly and could have been ahead inside the first three minutes, but Mario Balotelli's low shot from inside the box was kept out by Federico Marchetti.
Balotelli then found Kaka just outside the box, but the Brazilian's effort was too central and was comfortably held by Marchetti.
Kaka had two more chances in quick succession, but both times put his effort well wide of the right-hand post.
Riccardo Montolivo was the next to test Marchetti, but his drive was well tipped over by the Lazio stopper.
The hosts were unable to create another chance before the break and somehow the sides went in at 0-0.
