"With a crash in Germany, for example, he gave away a victory", he continued. "And at Paul Ricard he took too much risk with a move on Bottas in the first corner". But Toto Wolff has urged Lewis Hamilton and Mercedes to keep their feet firmly on the ground at the Circuit of The Americas, with the Silver Arrows boss expecting Ferrari to continue to "fight fiercely" in Austin, despite both titles looking increasingly likely to go to Mercedes. "Too bad for us, because with this vehicle it should have been even more exciting".
"Pressure is not necessarily fun, but it doesn't always exist where people often suspect from the outside".
Speaking to Frankfurter Allgemeine Zeitung, the German denied that pressure applied by Mercedes' Hamilton got to him.
"Honestly, you drive for yourself and for those who help you to compete at this level", he admitted.
"One guiding principle helps me", Vettel continued.
"The battle is far from over, so we approach Austin the same way as every other race: take it one step at a time, focus on our job and make sure we bring performance and reliability to the track", said Wolff. And I always like to reflect on what brought me to racing: "my enthusiasm and joy".
A victory for his chief title rival Sebastian Vettel at Spa cut Hamilton's title lead to 17 points, and suggested it was the Ferrari driver who had the momentum following the summer break.
While the duo are not believed to be rivals away from the grid, Vettel claims that they aren't exactly best friends either, with little contact being made between them other than in a professional capacity - making it hard for mind games to happen. "There is no direct contact", Vettel said.
"Things like "You have no balls" or "You were crap today" are no longer possible because every word is put on a golden scale".
Hamilton recently defended Vettel, saying that the German driver deserved "a little more respect" from the media.
