McLaren surprised by Glock's decision

Toyota's Glock decided to stay on dry tyres despite the heavy rain that hit the Interlagos circuit near the end of the race.

The decision meant Lewis Hamilton, who did pit for wet weather tyres, found himself in sixth place going into the final lap, needing fifth to secure the title.

But Glock struggled in the wet conditions and Hamilton managed to pass him with just a few corners left to secure the crown.

A delighted Dennis admitted Glock's decision was a surprise.

"It's great. It was a really difficult race," said Dennis. "We saw the Ferraris and Alonso go away we just couldn't race... you know we didn't want to race with them. So we had fourth and fifth to play with.

"Who would have thought Glock would stay out on dry tyres? We were just looking at it in the last two laps thinking; 'Do we fight for the position with Vettel, or do we let him go, and how's it going to happen?'

"Boy I tell you that was one hell of a call and we're pleased for the team, but delighted for Lewis."

Dennis also praised Hamilton, who became Formula One's youngest ever champion at 23, saying the Briton deserved the crown.

"We've got a couple of youngsters out there we are looking after, but he is very special you know," he added. "He has not just won a world championship, he is the youngest ever world champion.

"And he has done it so well, every statistic over the last two years, he has beaten. He has still finished this season with more points than any other driver over the last two years, so he deserved to win the world championship."
