Red Bull driver Sebastian Vettel recorded yet another start-to-finish win at the Singapore Grand Prix on Sunday to further extend his lead in the Formula One championship.

The German was in a class of his own under the Marina Bay lights, winning by a massive 32.6 seconds over Fernando Alonso and boosting his championship lead on the Ferrari driver from 53 points to 60, with six races remaining.

"We are in a very good position. To be honest I am not looking at the championship too much," Vettel said. "I am just enjoying it at the moment. Days like today and yesterday are what it is all about."
