How key was Lewis' first stint to the strategy?
"That first stint was really the reason that Lewis walked away with an incredible victory. He drove it perfectly. He started with a lot of management, setting reasonably slow lap times to start, making sure there was always traffic in what we call the 'Pit Window' so cars behind just couldn't stop.
"Then, he built the pace up very gradually and was able to pull away from the leaders behind. What it meant was, by the time we got to Lap 14, Whilst Vettel could stop, he still had a little bit of traffic there.
"Lewis' tyres were in a fantastic condition and he could just nail in the purple sectors - the fastest lap times - and come in just one lap later in a really good state relative to Vettel."

Would you have Pitted Lewis in case of a Safety Car after the first pit stops or were his tyres good enough to ward off any challenge from drivers on fresher rubber?
"Without question, the Soft tyre would have provided a little more protection than, say, Vettel's UltraSoft. But, ultimately, a car on brand new HyperSofts at the end of the race probably would have had the performance to get through.
"There's a little bit of evidence of that. Magnussen, for example, set the fastest lap of the race - a 1min 41sec, so quite a bit faster than the pace Lewis was running at. Now, it's difficult to overtake at Singapore - but a very heavily worn Soft tyre would probably not have stood a chance.
"So, to answer your question, it depends on what lap we look at. But it's highly likely that we would have stopped Lewis towards the end of the race and fitted fresh HyperSoft Tyres - even at the cost of boxing out of the lead of the race."
