“I've already said it but I want to say it again: I am proud of what the team has done and I want to thank everyone for that,” he said, “In particular, I want to thank Fernando, who has had the best season of his career: I must congratulate him because he never gave up and he managed to give more than anyone could have thought possible.
“It also gave me great pleasure to see a great second half of the championship by Felipe, showing we did well to keep him hanging on before we confirmed he would be staying. He has been with us for many years and this end to the season will be very important to him for the start of next year - and not just psychologically.
“We have had extraordinary reliability and this is down to [team principal Stefano] Domenicali and all his men, just as we have been very strong in our strategies and pit-stops - it's hard to find real errors in these areas.
“We haven't had a car at the same high level as the top two and we have to improve this. To win races, you have to start at the front, and to win the championship, you have to win races. I want to win the world championship and I expect a big step forward by the team in terms of organisation, methods and quality of work. If we can give a car that is capable of winning to our drivers then they will do the rest.”
