Bottas finished just 0.063secs ahead of Hamilton at the death to claim the 13th pole position of his Formula 1 career, and his second this season after converting his last in the season-opener in Austria into a victory.
Looking back over the past week since the misery of dropping out of second place with a tyre failure three laps from home in the British Grand Prix, Bottas said: "From last weekend to this week we've been working on everything we could improve with the car.
"For us, we've been able to find more in terms of set-up and, at least for me, driving-wise find a bit more.
"It's the same process that goes for this weekend. We've been able to go in the right direction through the weekend until the qualifying."
