Vettel became the youngest driver to win three world titles as he overhauled Ferrari's Fernando Alonso in the final third of the season.

"It all starts again from zero. We've all got the same chances in what will be a tough year again with a lot of races," the 25-year-old German said.

"So I'm just looking ahead. I'm not looking back on past races because I am convinced it doesn't give you a head start or an advantage.

"Obviously, the expectations are still there, but more than that we expect ourselves to do well again, so there is a lot of pressure.

"Right now there is excitement to get back into the car, start testing, then go racing and find out where we are. It's one thing to do all the talking now, but as soon as you have the helmet on, you simply want to perform and do your best."
