Paul Hembery: "The wet conditions yesterday morning meant that the teams had to work hard in the morning to make up for time lost gathering data on the slick tyres. All of them managed to find plenty of pertinent information: vital not only for qualifying today but the race tomorrow as well, which we expect to be dry. During the final free practice session this morning we saw a deflation on the rear left tyre of Sergio Perez. First findings show that this was unequivocally caused by a cut in the inner sidewall: something went into the tyre, pierced it, and then came out again, in the direction of travel.
"Whether that was a piece of debris or the edge of a kerb is hard to say at the moment and it is important to point out that this incident was unrelated to any of the delamination issues we have had in the past. Congratulations to Lewis Hamilton for sealing a great pole position with a stunning lap at his home grand prix. Yesterday's rain meant the fans didn't get a chance to see much on-track activity but today was action from start to finish. We're looking forward to an exciting grand prix tomorrow with between two and three pit stops per car if conditions stay largely the same."
