Fernando Alonso has hailed Ferrari's turnaround in form that has thrust him into the lead of the Formula One world championship as "amazing", but knows more is required if he is to win a third title.
Despite a tough pre-season, Ferrari dug deep into their reserves of wealth and manpower to provide Alonso with a winning car by the second race of the season in Malaysia and he also claimed a triumph on home soil in Valencia 12 days ago to become the first driver to win two grands prix this year.
"We are definitely quite happy with the situation now in terms of points. It's a situation we were not expecting," Alonso said. "But we are also very honest with ourselves because in terms of performance we know there are still a few cars quicker than ours."
He went on: "We need to close that gap in the next couple of races if we want to fight for the championship, so we are still not completely happy. If not, and if we don't work better than the others, we know sooner or later they will be in front."
Alonso appreciates, though, what has been achieved by Ferrari to get him on to the top of the podium from a position of doom and despair just five months ago.
He added: "The job the team has done over the last few months has been amazing, recovering maybe 1.5 seconds, or something like that, that we were off the pace in Australia.
"This is good news, not only for this championship or for this moment, but also for the near future of the team.
"We faced some difficult times, but now we are definitely going in a good direction.
"But as I've said, there is still a lot to come from the team in the next couple of races, the next couple of months, in terms of performance in the car.
"So hopefully they will continue to work as they are working now."
