The championship is very delicately balanced heading into the final two rounds and the psychological approach of the top five drivers is becoming increasingly important. The title can be just as easily lost as won at this point, and the drivers' split-second decisions in Brazil and Abu Dhabi will be crucial.

Fernando Alonso is currently leading the championship and I have to say he appears to be very cool. He's won the title twice before, which is a big advantage, and if I was going to pick one of the top five drivers to defend the title going into the last couple of races, I'd pick him. It's now up to his rivals to put him off his stride and it will be very interesting to see how they attempt to do that and if they succeed.

I'm a racer, so personally I'd rather be chasing the championship than defending it. If you're chasing, it's always more acceptable to push the boundaries and go a bit quicker than you should, which suited my approach to racing. If you're leading you're told to keep your speed down and not to overdo it - that always seemed a bit boring to me.

But of course I never won the title; I finished second four times, lost by a couple of points one year and by one the next, all for different reasons. The closest I came was in 1958 when I entered the final grand prix in Morocco needing to win, secure the fastest lap and have Mike Hawthorn finish lower than second.

I went there knowing exactly what I needed to do and crossed the line with the win and the fastest lap, with Mike back in third. Of course Mike's Ferrari team-mate Phil Hill did the correct thing and let Mike through to take second, allowing him to win the title by a single point. Incidentally, there was never any ill feeling about that from either side, which should also be the case if Alonso wins the title for Ferrari this year.
