Nico Hulkenberg will line up in P5 tomorrow, achieving a career best in qualifying at Monaco.
"Today I felt the most comfortable ever, even compared to two days ago in practice," Hulkenberg said.
"Usually, in practice, you get in and you feel a bit unhappy and uncomfortable, but here this weekend, from lap 1 I've had good vibes from the start."
Hulkenberg underlined the fact that he felt very confident in the qualities and balance of his VJM09 chassis which has improved greatly since it received a series of upgrades in Barcelona.
"The car definitely made a huge step forward in Barcelona, and we know that this type of track, with low-speed corners, suits it much more than in Spain so that's good.
"Obviously, we'ge got the main job on our hands tomorrow which we need to focus on. It could be a tricky one with the weather forecast but we'll take it as it comes and try to do another good one."
With regard to tomorrow's forecast which has scheduled the risk of rain in the race, Hulkenberg believes there's no point in worrying one way or the other, and he will accept whatever the elements bring to the day.
"I don't care, I'll take it as it comes as we really have no choice, we have to perform with what we're seeing and faced with, and that's what we will do."
