How Vettel can become champion in Singapore

Four drivers have won in 2011, but one man has won four times more than anyone else - Red Bull’s Sebastian Vettel. With eight victories and only one non-podium finish - a fourth in Germany - he now stands on the brink of a second successive drivers’ title.

A third place in this weekend’s 2011 Formula 1 Singtel Singapore Grand Prix could be enough to see the German crowned champion with five rounds to spare. But, of course, Formula One is never that simple. €t all depends on how his key rivals fare at Marina Bay.

They (in championship order) are Ferrari’s Fernando Alonso, McLaren’s Jenson Button, Red Bull’s Mark Webber and McLaren’s Lewis Hamilton.
