"I think we have to be happy with the performance today," said Alonso, whose Ferrari team (290 points) overtook McLaren (284) for second place in the constructors' standings behind Red Bull (367).
"We are moving in the right direction. We just need a little last step to be as competitive as Red Bull."
Brazilian Felipe Massa continued his late season resurgence with fourth for Ferrari.
