Singapore GP 2013: David Coulthard's inside track Who to watch Marina Bay is a stunning track illuminated by the wattage of thousands of bulbs, set against a backdrop dripping with history, from Raffles Boulevard to Anderson Bridge. This race is rapidly becoming one of the hottest fixtures on the calendar, and not just because it is 30C at night. I would expect Mercedes to push Red Bull hardest, based on their performance at the last street race, in Monaco. Where the race will be won F1 is all about risk and reward and here drivers gamble that bit more than usual when they go for a pass. There is little room for error with the walls so close. But there are two DRS zones, so overtaking is by no means impossible. Qualifying will be important and then it will be all about focus during the race. It is too early to say how the tyres will pan out but with the chicane at T10 removed the track is faster than ever. Sub-plots Fernando Alonso back to McLaren? Stranger things have happened. I think it is probably an attempt to destabilise Ferrari and Alonso - to see how fractious their relationship really is - while at the same time making it clear that McLaren are keen. But it runs the risk of destabilising McLaren's own driver line-up. Jenson Button is big enough to take it in his stride, but Sergio Pérez is a young guy and may get unsettled.
