NEW DELHI - The Formula One season that began with seven different winners in the first seven races is in danger of ending with one man, Red Bull’s Sebastian Vettel, chalking up seven wins in succession.The 25-year-old German has already won four in a row, the first time the double champion has done that in a single season, and is fancied to follow up Sunday’s Indian success with another in Abu Dhabi next weekend.Red Bull team boss Christian Horner kept his focus on the figure three - the three races remaining - rather than allowing anyone to get carried away with talk of seven, however."Talk is cheap at the end of the day and I think it’s down to what you do on the track,” he said when asked about comments by Ferrari’s Fernando Alonso who said he was sure he could still win the title.Reigning champion Vettel leads Alonso, who finished second in India on Sunday, by 13 points after arriving in India six points clear."We can all prophesy but ... our focus is now on Abu Dhabi, to extract the most out of the car, the drivers, the strategy, the reliability that we can. It’s going to be a question of having three perfect weekends,” said Horner.The principal, whose team could clinch the constructors’ title for the third year in a row on Sunday, was well aware that one retirement could swing the pendulum in completely the opposite direction in the drivers’ standings.
