Massa says Hamilton can be main threat

With Hamilton having taken the lead of the title chase after last weekend's Spanish Grand Prix, Massa says he is in no doubts that Hamilton has was it takes to lead McLaren's challenge in 2007.

"It is Hamilton who leads right now and I have spoken quite a bit to him: he is definitely strong and is not bothered by pressure," said Massa in his official website blog.

"At the moment, you cannot say that Fernando or him are the better driver, but if the situation continues like this, then maybe Lewis can even be more dangerous than Fernando, given his championship position and how he goes in the car.

"At the moment he seems more comfortable in the car than Fernando. We need to keep an eye on that, because he can be a dangerous threat."

Massa believes that Ferrari cannot afford to relax in their fight to ensure their car is better than McLaren. And, despite taking two wins and three pole positions this year, he thinks that nothing is guaranteed for the rest of the season.

"What is unusual is that after three poles and two wins in a row, I am still only third in the championship," he said. "It shows we are moving in the right direction and that we have the momentum, but it also shows we need to keep working hard.

"I am the driver with the most wins and poles at the moment, but we need to have our feet on the ground and keep pushing, because the whole championship is going to be very tight.

"If you look at the second (Q2) part of qualifying in Barcelona, where it is easiest to see which car is really quickest, then it is clear how close it is between us. The advantage is not so big.

"But I have to say that, in the race, with our car and set-up and how we manage the tyres, as well as having a great strategy, we had a better package than McLaren. This doesn't mean we have a real advantage, so we need to keep improving the car."

Massa also has no remorse for his collision with Alonso at the first corner in Spain - and instead is proud that it shows how much he has moved on since coming under fire for not defending his position in Malaysia.

"Sure, it turned out to be a tight battle at the first corner, as everyone could see. What happened there showed that I am not scared of being aggressive and that I can be a fighter.

"I know I am up against some very tough opposition, so this proved that I can be tough too. And then, the way I drove after the start shows that after what happened in a similar situation in Malaysia, I am able to learn a little bit and move forward."
