Sergio Perez thinks he is ready for the pressure of racing for a top team.
“He might think he understands it, but he doesn’t,” said Whitmarsh.
Perez, 22, acknowledged: “Of course there is extra pressure when you’re driving at the front.
“I have to get used to that, but I have already had a taste of it at Sauber,” he is quoted by the Dutch website formule.nl.
“When I was on the podium I was a superstar, and when I didn’t do well, I was the driver who made too many mistakes,” admitted Perez.
Still, Perez said he expects to succeed in 2013.
“I want to win titles with this team, so I want to do it next year,” he said.
“It will be a long season, so it’s important that I am well prepared from the beginning in order to satisfy their expectations.”
