Speed: no doubts about Toro Rosso seat

Toro Rosso are the only F1 team yet to confirm their 2007 line-up, leading to uncertainty about the future of Speed and Italian teammate Tonio Liuzzi.

Speed, however, is adamant that his position is safe.

"For me, it's always been sure. For whatever reason, they haven't announced it officially, but I very much doubt anything will change. We're not worried. I mean, everyone I have talked to within Red Bull and the team - for everyone it's sure," the American told SpeedTV.

Toro Rosso owner Gerhard Berger said last week both Speed and Liuzzi were on pole position for the racing seats, although the Austrian admitted he was in no hurry to make an announcement.

"Of course Tonio and Scott are in pole position for the STR drives in 2007," said Berger. "We just had to sort out other things. We are not in a hurry to name drivers."

Despite the uncertainty about his future, Speed, who made his Formula One debut last year, is upbeat about the upcoming season, when Toro Rosso will use Ferrari engines in their hope of moving up the field.

"The Ferrari (engine) and the new car are all going to be ready at the very beginning of February," Speed added. "I'm very excited about it and that's what I'm looking forward to the most.

"That will be the package that takes us from running in the back to being in the upper mid pack. It's going to be a completely different season next year."
