Milan leaped into Serie A top spot after snatching a 1-0 win over Napoli on Sunday, thanks to German Denis' last-gasp own goal. Milan had to wait till the 87th minute when Ronaldinho's free-kick was accidentally diverted into the net by the Argentine forward's header. The Rossoneri are now leading Defending champions Inter Milan by one point. The Visitors were outnumbered during the entire second half, as defender Christian Maggio received his marching order on 44 minutes. Barzilian ace Kaka haplessly squandered several clear-cut chances during the second half as Carlo Ancelotti's men couldn't open the scoring despite their opponents' numerical disadvantage. Milan coach Ancelotti sent frontline duo Alexandre Pato and Filippo Inzaghi into battle but couldn't break the deadlock, until Denis' own goal ended the game in the Rossoneri's favor.
