Vettel ecstatic after 'unbelievable' pole

Vettel, 21, became the youngest driver to clinch a Formula One pole position, beating previous record holder Fernando Alonso by over five months.

It was also Toro Rosso's maiden Formula One pole.

Vettel took full benefit from the treacherous condition to beat all his rivals and complete a perfect day for his Italian team.

"Unbelievable, incredible," said Vettel. "I was joking with my engineers that if it was wet we have to go for pole. The conditions were very difficult today. With water you never knew what to expect. At Ascari there was so much water and I lucky to not lose the car because of aquaplaning.

"I dreamed of being on polo. There are two Italian teams, most people know of the big one, but now people know of the smaller one - Scuderia Toro Rosso."

He added: "What can I say? It will take some time (to sink in) for sure. It was my dream one day to drive an F1 car and then my target is to fight for pole positions and race wins.

"It was a day I didn't expect. It feels fantastic, incredible, being part of F1, and fighting against those drivers with me is fantastic."

Vettel admitted he felt very confident with his car following some overnight changes.

"We had already had some wet practice on Friday and I didn't feel very comfortable," he said. "Overnight we did some changes, we did not know what to expect, how much rain there could be, we found just the right thing.

"After free practice today I was very happy with the car in the wet, with a very good balance. When you feel confident in these conditions then it is a huge advantage, that is the key. If you don't know how your car is you are not even trying."

Teammate Sebastien Bourdais completed an historic day for Toro Rosso by qualifying in fourth place.
