Massa says his approach hasn't changed

The Brazilian was pushed down from pole to third at the start in Sepang, then went off the road trying to pass Lewis Hamilton and could only finish fifth.

But he then proceeded to dominate the Bahrain and Spanish Grands Prix and is now within three points of the championship lead.

Massa said the only change was that Ferrari had got on top of earlier mechanical problems and could use their full potential at Sakhir and Catalunya.

"They were two fantastic races," he told autosport.com. "Starting from the free session and qualifying, I think we could use everything we did in the winter tests in the last two races.

"There were so many reasons we could not start the season like this, mainly for technical problems, and now we managed to put everything together."

He added that he had also learnt from his Sepang mistake and focused more on protecting the inside at the starts.

"Honestly I did not change anything (mentally)," said Massa.

"The only thing I can say is maybe in Malaysia I was sleeping at the start, and in the first corner I was on the outside. That's why, if Fernando (Alonso) was outside he could not pass me.

"Even in Malaysia I could have tried (to stay ahead on the outside) but I could have finished like Fernando (did in Spain) so we saw that who is on inside and who is on the preferential side in the corner has more chance. At the last race I was aggressive and I tried to keep the inside line in both of the races and I was successful."

Despite winning two successive races, Massa said he is determined to remain realistic about his title prospects.

"It was really a great achievement but this is nothing," he said. "Even (though) we won two races we have 13 races to go and other races will be important.

"Even you win you never have enough time to be satisfied, (you always) need to work more."
