Brazilian GP: Pirelli Sunday quotes

"With the weather so unpredictable, some teams used strategy by putting one driver on slicks and the other on intermediates, in order to have real-time data about the relative performance of the tyres. A further variable affecting the tyre strategy was also the lengthy safety car period in the first half of the race, which reduced the amount of wear with the cars still on heavy fuel.

"Even when the rain was falling hard in the first half of the race, the medium tyres still generated enough heat and grip to enable Jenson Button to maintain control without going onto the intermediate. Congratulations to Red Bull and Sebastian Vettel, who adapted their strategy calls brilliantly to changing circumstances, as well as to Fernando Alonso and Ferrari, who pushed them every inch of the way.

"We'd also like to congratulate Jenson Button, who got the very best out of both the slick and the intermediate tyres, and take this opportunity to pay tribute to Michael Schumacher: a great champion and fantastic ambassador for the sport, who ended his final grand prix in the points."
