What I have felt at McLaren is good professionalism, a team that is very determined and focused on the championship. There is a new atmosphere within the team, and I saw that when I went to the factory and met all the people. They are so excited. They really think that after a few years without success, this is the year to come back. No-one has doubts. That was a complete surprise to me, yet from my point of view, it was great to see all that optimism, and I feel more ambitious now - a completely new man. Sometimes after a tough season and when the winter arrives, you want to test as late as possible, to be on your holidays as much as you can. But now it's the opposite. I want to be in the car. I feel like when I arrived in Formula One six years ago. I just want to drive.
