( CNN ) -- Nine-man Inter Milan surged nine points clear of city rivals AC Milan at the top of Serie A with a dramatic 2-0 win in the San Siro on Sunday night . Diego Milito gave the reigning champions the lead in the 10th minute , but they were forced to much of the game with 10 men after Wesley Sneijder was sent of in the first half . Goran Pandev 's 65th-minute goal sealed the win for Jose Mourinho 's side , who then saw Brazilian star Lucio shown red in stoppage time before Ronaldinho saw his penalty saved at the end of a dramatic derby which could go a long way to deciding the outcome of the title race . Sneijder hit the outside of the post before Inter took the lead as Goran Pandev 's ball sent Milito clear to beat Dida in the Milan goal . Dutchman Sneijder saw red on the half hour mark as his sarcastic gesture after Lucio had been pulled down saw him given his marching orders under strong protest . Milan tried hard to level at the start of the second half as Julio Cesar saved a close range Clarence Seedorf header from a David Beckham corner before Ronaldinho was just wide with a volley . Beckham , who earned a yellow card in the first half , sent in a series of dangerous crosses from the right , but it was Inter who sealed the win through Pandev 's superb curling free kick . In injury time Lucio was sent off for a second booking as he conceded a penalty but Ronaldinho 's effort was saved by Cesar to complete a miserable night for his team . Earlier on Sunday , Napoli won 2-0 at Livorno to move to within a point of third-placed AS Roma while Palermo beat Fiorentina 3-0 to go fifth .
