MANILA, Philippines – Red Bull driver Sebastian Vettel is looking forward to this weekend’s Formula One Grand Prix at the Suzuka Circuit, where he could clinch the championship. Vettel is on the brink of a fourth successive title after winning last Sunday’s Korean Grand Prix from pole position. His fourth victory in a row gave the 26-year-old German a lead of 77 points over Ferrari’s Fernando Alonso with five races remaining. If Vettel wins in Japan on Sunday, and the Spaniard finishes ninth or lower, then it’s game over. Vettel won in Japan last year and he rates it as his favorite circuit. Despite the charge to the title, Vettel and the British-based team are taking it one race at a time.
