Vettel not worried about STR's future

The Red Bull boss said earlier this month that he plans to sell the Italy-based squad in order to focus all efforts on Red Bull Racing.

Vettel, who has a three-year contract with Red Bull, admitted he was surprised to hear the news, but he sees no reason to be worried.

"Very surprised," Vettel told the official Formula One website. "As a driver you are usually one of the last people to come across in-house developments. Fact is I read it in the press - like everybody.

"What does it mean for me? I want to race this season as well as possible - there is no reason now to be worried.

"When you saw the people preparing the car for the race (in Malaysia) there was not one who was thinking about what will happen in one or two years - everybody was totally focusing on the moment."

The Toro Rosso driver, who has shone in last year's car so far this season, says he is not thinking about his future yet, and admits he is happy where he is.

"I usually don't talk about my contract situation," he added. "And for the moment I am happy where I am - and focused completely on this team. The races ahead have my full attention.

"It was always my philosophy to go step by step and it has served me well so far, so what will be at the end of the season lies too far ahead."
