Although Alonso started the grand prix from pole position, the Spaniard lost out to Button off the line as the Brit pulled off a flying start.And with Championship leader Lewis Hamilton out of the grand on the first lap with a broken steering arm curtesy of a coming together with Felipe Massa, it was a perfect opportunity for his title rivals to make up some ground on the 2008 World Champ.
Button put up with immense pressure from Alonso, who maintained a second gap between the two as they traded fastest laps with Massa always in the background in third place.
However, it was the pit stops that decided the race as Button pitted on lap 37, handing the lead over to Alonso, who pitted a lap later.
Alonso emerged marginally ahead of Button and although the reigning World Champ tried to put his warmer tyres to good use and overtake the Spaniard, he was unable to.
From there it was Alonso who had to put up with the pressure applied by Button, however, it wasn't long he appeared to break Button's spirits and pull away from the McLaren driver to claim Ferrari's first home victory since 2006.
Massa was third with Sebastian Vettel, who came in for his mandatory pit stop on the very last lap of the grand prix, in fourth place.
