"The team did a perfect job with the setup of the car," said Alonso, who is now third in the overall standings on 43 points after three races - six points behind Raikkonen and nine adrift of Red Bull's triple champion Sebastian Vettel.
"It was a fantastic race for us from the start. There were no big problems and the tyre degradation was better than expected. It feels great," he added.
"In the two races we've finished we have got second place and victory so our start of the 2013 season is very good."
