With 60 minutes on the clock for drivers to sort themselves out in the correct order for qualifying, the pressure is on. Pole position isn't as crucial at Spa as it can be at other tracks, and overtaking is possible, but starting as far forward on a Saturday as possible can make all the difference to a race strategy. We've only had three different polesitters so far this season, can anyone other than Sebastian Vettel or the Mercedes duo make it to the top?
