Team by team analysis of Sunday's Italian Formula One Grand Prix (listed by championship order): MCLAREN (Fernando Alonso 1, Lewis Hamilton 2) Alonso took his fourth win of the season and McLaren's fourth one-two. It was the Spaniard's 19th career win and his team's first one-two at Monza. The double world champion led from pole position to reduce Hamilton's championship lead to three points with four races remaining. McLaren moved 23 points clear of Ferrari. FERRARI (Kimi Raikkonen 3, Felipe Massa retired) Massa retired on lap 10 with a rear suspension problem. He had banged wheels with Hamilton as the Briton passed him into the first corner. Raikkonen struggled with a sore neck after crashing in Saturday practice and was also overtaken by Hamilton. The Finn now leapfrogs Massa to third in the championship, 18 points behind Hamilton. BMW SAUBER (Nick Heidfeld 4, Robert Kubica 5) Heidfeld took BMW's eighth fourth place of the season. Kubica clocked the top speed of any driver (351.7kph). It was the sixth race in a row that the team had finished with both cars in the points. With 86 points and four races remaining, BMW set their sights on 100 points by the end of the year. Their third place in the championship appears safe. RENAULT (Heikki Kovalainen 7, Giancarlo Fisichella 12) Kovalainen finished where he started on the grid, thanks to Massa's retirement. Fisichella was hit by Coulthard's Red Bull at the start, damaging the rear end plate. The team turned his engine down towards the end to save it for Spa. WILLIAMS (Nico Rosberg 6, Alex Wurz 13) Three more points took the teams' tally to more than double that of engine suppliers Toyota. Rosberg equalled his best finish of the year and collected points for the third race in a row. Wurz started with a heavy fuel load and suffered after qualifying 13th. RED BULL (Mark Webber 9, David Coulthard retired) Webber fought with Button and Rosberg early on but said the inconsistent balance made it one of his hardest races. Coulthard hit the back of Fisichella's car in the middle of the first chicane, breaking his front wing which was then pushed under the car and wrecked the steering. TOYOTA (Jarno Trulli 11, Ralf Schumacher 15) Both had a one-stop strategy. Trulli made a poor start, losing three places. SUPER AGURI (Anthony Davidson 14, Takuma Sato 16) Sato had a brake pedal problem on the formation lap and the front brakes caught fire on the grid. The safety car stint helped cool them down. A first lap impact with Vettel damaged Davidson's diffuser. HONDA (Jenson Button 8, Rubens Barrichello 10) Button took his and Honda's second point of the season but his was still a frustrating race. He also flat-spotted his front right tyre in his first stint. The team may be making progress however, as evidence by having both cars in the top 10. TORO ROSSO (Vitantonio Liuzzi 17, Sebastian Vettel 18) Both cars at least reached the finish. Vettel ran into Aguri's Davidson in the second chicane on the first lap, losing his front wing. SPYKER (Adrian Sutil 19, Sakon Yamamoto 20) Spyker used their revamped car for the first time, but more work is clearly needed to lift the team..
