"But does it mean we can stop Brawn GP? That's the aim but it's been a strange season so far so who knows.
"Our target is to always be the best and, right now, that means beating Button and Brawn GP."
Ferrari and McLaren have dominated the championship in recent seasons but the Woking-based team are fourth and the Italians only have one more point than Force India.
Domenicali admitted his outfit were still off the pace of McLaren, who finished fourth on Sunday through Britain's Lewis Hamilton.
He added: "We made a good step in the right direction in Bahrain but it just wasn't as good as McLaren's. They're clearly a step ahead of us."
Had one of the Ferraris not finished in the points in Bahrain then it would have been their worst start in their championship history and Domenicali's job would almost certainly have been on the line.
But the Italian, who took over the job from Jean Todt last season, admitted he would be under even greater pressure if the changes in Barcelona failed to push Raikkonen (left) and Felipe Massa up the grid.
"At Ferrari, the expectation is always success," he said.
"There's pressure, for sure, but I don't mind about the pressure, I just care about us making a winning car."
