Monza - Team chief Maurizio Arrivabene shrugged off suggestions that Ferrari had chosen wrongly by adopting a two-stop strategy for Sunday's Italian Grand Prix with a laugh.
The Italian boss said he was aware of criticism of the team after they finished third and fourth behind the two Mercedes.
"I was hearing some comments that maybe one stop was a better strategy," he said. "I just laughed with our engineers about this...
"You have to protect yourself, if you go for one stop. We were doing the opposite. We were aggressive.
"If we did the same strategy as them, we would be 11 seconds slower than we were - so, for us, we were on the faster strategy."
Four-time champion Sebastian Vettel of Germany came home third six seconds ahead of Finn Kimi Raikkonen, the 2007 champion.
Vettel said: "We knew it would be tough against Mercedes and it was, but we did a great job, finished third and fourth, which is the optimum we could get.
"We had a different strategy. We had fresher tyres at the end, so it was expected that we would be quicker and catching up, but it was not enough to put them under pressure.
"We extracted our best race and it has been a while since that's been the case."
