Sebastian Vettel insists he is perfectly happy at Red Bull amid Ferrari rumours

The two-time champion has a contract with the Milton Keynes-based squad until the end of the 2014 season, but the German has again been linked with a move to the Ferrari team.

Vettel, however, says he feels perfectly happy at Red Bull, with which he has won his two titles.

"I've been wearing a Red Bull helmet for almost my entire career. It is difficult to imagine another kind of life if you are so used to it," Vettel told AUTOSPORT when asked about his plans after 2014.

"It would be like when you turn 18, 19 and move out of your family's home. I am very happy where I am right now and I don't want to move on to anywhere else."

Vettel, who dominated the 2011 season with 11 wins and 17 podiums, is currently in second place in the standings, having won just one race this year.

The German says consistency - and not only wins - will be very important this year given how tight the fight at the top is.

"People only remember our wins, but they forget a bit how tight it often was," he said. "Yes, we won some races in which we did not have the strongest package.

"This year there are much more candidates to win races than before. Therefore it gets more essential to collect as many points as possible in every race."

With six different winners in the first six races of the season, Vettel believes it is vital to get everything right during the weekends in order to be fighting for victory.

"From the first day of winter testing on I had confidence in our car. We have not got out the most of the potential though we make steadily progress. And troubles with tyres concern almost everyone, not us alone. It simply depends on who will be doing the better job."

And the world champion reckons the unpredictability of this year's races is translating into a good show for the fans, despite some criticism about the racing being artificial.

"If you look back ten years, there was heavy criticism of a boring F1 because of Michael (Schumacher) winning all the time. Now we hear F1 is unpredictable and a lottery.

"You cannot satisfy all people every time, but I think we have a good show, a lot of overtaking, good action now. There is more tension - for people who watch and for us inside the cars. I think I like the way it goes, however, we have to be careful not to create something artificially."
