Vettel focused on winning more titles

Red Bull's Sebastian Vettel says his thirst for success has not been quenched by winning his latest world title.

Vettel, who sealed a fourth consecutive drivers' world championship at the Indian Grand Prix, visited the Red Bull factory to celebrate his success, with a news conference followed by a meet-and-greet with the employees.

And, Vettel confirms he is very happy with the team and praises them for taking a risk by promoting Daniel Ricciardo from junior team Toro Rosso to be his team-mate next season, a move similar to the one he made in 2009.
