Mercedes boss Toto Wolff acknowledges that Ferrari is catching Mercedes after Sebastian Vettel kept in touch with the pacesetters in Brazil.
The German finished just 14secs behind winner Nico Rosberg, and 6secs behind Lewis Hamilton. It was his 13th visit to the podium in 2015.
“I am anticipating a robust challenge from Ferrari because they have done some clever moves,” said Wolff. “And they have definitely caught up. You can see that even towards the end of the race today Sebastian was not very far away, when Lewis and Nico were pushing flat out biggest gap was seven seconds. That is not a clear-cut dominant race win. I think we will have a situation where Ferrari will be a very important competitor.
After a relatively low-key race in Brazil Wolff was asked if the sport needed a further step from Ferrari to improve next year’s show he said: “I think we are not relying on it. We wouldn’t want to rely on it! What you can see again with aerodynamic efficient cars, it is very difficult to follow. You destroy your tyres and when you destroy your tyres by attacking and being close for a couple of laps you have no performance left in the tyres. It is nothing new.
“We have seen this the last decades, always the same. And in the race the top guys were running away at the front, there wasn’t any rain and not a lot of incidents in the race. It is like a good and a bad football match, and today we have probably seen one of the boring football matches.”
