Its been 3 races since Mr Vettel was unable to swing the magic wand his way.Mounting pressure from the Ferrari's McLaren? Both of the Red Bull drivers have called for a rethink could just hint at a bit of unrest behind the scenes at Red Bull. Vettel was a bit critical of his pit stop strategy in Hungary. Vettel had a chance of winning the race, but was edged out by McLaren’s Jenson Button, and because the Ferrari team and the McLarens have become more and more competitive as the season has worn out, the gauntlet has been thrown down to Red Bull to improve. There are just eight races left in the season, and as long as Vettel keeps coasting home with podium finishes, there is not going to be too much the rest of the field can do about that.
