Defending world champion and Red Bull driver Sebastian Vettel has admitted that he would not rule out a possibility of a future move to Ferrari.

Fernando Alonso and Kimi Raikkonen are the two drivers leading Ferrari this season and despite their not so good run in this year's Formula 1, their team boss Marco Mattiacci has admitted the current two drivers will be leading Ferrari next year.

Vettel, who won four championships with Red Bull has had a rough start to the 2014 season and is 95 points behind Mercedes driver Nico Rosberg, who is on the top with 165 points. The 27-year-old German says he is happy with his current employers, but has left the option open for a future move to Ferrari.

"Right now I'm very happy where I am and I'm really not thinking about what I'll do in the future, but I wouldn't rule out racing for Ferrari. You should never say never in life, but right now I'm very happy," Vettel told the Spanish newspaper AS.

Vettel won last year's race in front of his home fans and the Red Bull driver would be hoping to win the 2014 German Grand Prix this weekend. However, the four-time World champion believes it will be a tough task and podium finish would be a good result at Hockenheimring

"There's always a chance of winning, but I do think that finishing on the podium would be a good result in Germany. We try to improve every day. We're competing at the highest level, against amazing drivers and teams and it's not easy to win," Red Bull driver said.

The German driver has ruled out the possibility of bouncing back in the second half of the ongoing F1 season.

"It's not that it's affecting my style of driving, I've had a lot of reliability problems this season, and also in terms of speed, and I'm still nowhere near where I want to be. I have to work on my driving and overcome it. I think I can do it," Vettel concluded.
