Massa narrowly missed out on failing to finish himself following a first corner incident with Alonso that culminated in a post-race war of words between the duo.
In front of a 140,000 home crowd, second on the grid Alonso tried to overtake pole-man Massa around the outside going into turn one.
The Spaniard cut in, only for the two to touch, with Alonso taking a run onto the gravel that relegated him to fourth.
Massa claims he had the inside line; Alonso that he was ahead; in the end it was a messy squabble.
"When you are fighting for the championship, it's very risky to be so aggressive in the first corner," said a disgruntled Alonso.
"If you look at my car, the sidepod and rear have been touched.
"That shows everybody who arrived first into the corner. I was more than half a car in front."
That brought a dismissive shake of the head from Massa, and a wry smile as he countered: "I was inside, so I don't understand his point.
"As long as I am inside, I will stay there. I won't move. If anybody was aggressive, it was Fernando, not me.
"If I am wrong, then I am the first to say I have made a mistake.
"But this time don't tell me I've made a mistake. Come on, this is racing, Formula One, the first corner.
"So when I make a mistake I'll be the first to say. Don't worry."
