Alonso: Title rivals fear mistakes

Alonso has good experience of title showdowns following his title successes in 2005 and 2006, and thinks the pressure on drivers changes when the end of the season gets near.

"More than the pressure is also the worry about making a mistake or that something goes wrong in the car," said Alonso.

"You think constantly during the weekend that everything has to go right and you cannot do any mistake driving, or you cannot make a mistake with the car in terms of breaking any part.

"You spend too much effort thinking that anything can go wrong and this is putting some pressure to you every time."

Alonso believes the situation is particularly worrying for the title rivals this year because of Massa's engine failure in Hungary - which highlighted how late in races things can go wrong.

"Every race will be difficult to manage and unpredictable to the last moment in Brazil when you take the flag.

"Massa was winning the race very clear in Hungary and on the last lap you have engine failure, you lose ten points, and this can happen to anyone. And it maybe happens to Lewis as well."
