(CNN) -- A seventh minute goal from Brazilian teenager Alexander Pato proved enough to give AC Milan a 1-0 home victory over Fiorentina in a match totally dominated by Manchester City's $150 million bid for playmaker Kaka this week.

The goal was created by David Beckham who beat two defenders to a loose ball. He poked it back to Marek Jankulovski who played in Pato inside the penalty area.
There still appeared no danger to the Fiorentina goal, but Pato hit a stunning strike from the left that went in off the far post.
Fiorentina should have equalized on 66 minutes when Juan Vargas got to the byline and crossed to Mario Santana but the Argentine put his shot too close to goalkeeper Christian Abbiati who managed to save.
The result leaves Milan in third place on 37 points, six points behind leaders and city rivals Inter, who have a game in hand. Jose Mourinho's side travel to Atalanta on Sunday.
Jankulovski collected a late red card for timewasting, but Milan held on to secure the three points.
Meanwhile, Milan supporters made their opposition to the Kaka bid, and his possible departure, perfectly clear throughout the match -- unveiling a host of banners and singing songs pleading with the Brazilian to stay at the San Siro.
Reggina remain deep in relegation trouble after suffering a 1-0 defeat at the hands of Siena. Mario Frick's goal 15 minutes from time was enough to give the Bianconeri three points which sees them leapfrog Sampdoria and move up to the relative comfort of 14th spot.
Siena in contrast, stay second from bottom and could slip to the foot of the Serie A standings if Chievo beat Napoli on Sunday.
