AC Milan extended their advantage at the top of Serie A to 12 points with just four matches of the Italian league season remaining with a 2-1 victory at AC Siena.
Carlo Ancelotti's side moved well clear of AS Roma, who now have two matches in hand on the leaders and visit Modena FC on Sunday night. Champions Juventus FC travel to Parma AC earlier the same day.
Prolific Ukrainian striker Andriy Shevchenko put Milan in front midway through the first half with his 21st goal of the season, reacting quickest to turn the ball into the net after Rui Costa's shot had been parried by Siena goalkeeper Marco Fortin.
However, just 12 minutes later the striker's error enabled Siena to draw level. Shevchenko handled inside the Milan penalty area and former Italian international striker Enrico Chiesa made no mistake from the spot.
Siena lost midfield player Simone Vergassola to a second yellow card eleven minutes from time, and a minute later Milan secured all three points, Brazilian playmaker Kaká heading in to give the visitors victory.
