Sebastian Vettel believes that Mark Webber's superiority in the third sector of the lap at Barcelona was the difference between the Red Bull teammates in qualifying.
The Australian edged his young teammate in all three segments of qualifying on Saturday, and the pair effectively fought an exclusive battle for pole position in Q3. Despite Vettel briefly moving to the top spot on his final lap, Webber was able to find more time again to take his second pole of the season.
"Mark did a very good job today – a very smooth run through all the qualifying sessions," said Vettel. "He always seemed to beat me too much in the final sector, [so we] have to look at the data and see where I can improve."
The 22-year-old added that despite Lewis Hamilton being 0.8sec adrift in third, Red Bull must stay focused on converting its dominance into a result on Sunday.
"I think we are enjoying ourselves," he said. "Obviously Mark wants to beat me and I want to beat him, that is not a secret. Even though the time looks comfortable, we have to keep our feet on the ground because tomorrow is the most important day.
"So far we have been quick and done a good job. If we are here tomorrow and we can confirm that then I would be very pleased."
