Mark WebberMark Webber says he can still win the Formula 1 World Championship despite crashing out of the Korean Grand Prix in wet conditions and potentially losing his points lead in the process.

The Australian spun out of second position after running wide onto a kerb, then struck a wall before being collected by Nico Rosberg's Mercedes in a race badly affected by long delays because of rain. The accident occurred as his title rival and teammate Sebastian Vettel was extending his lead at the front of the field.

Asked whether he can still win, Webber said: "Absolutely. "Positions are not really important at the moment, the points are the important thing.

"They can change very quickly and this is my second non-finish of the year, but there are still two races to go and I will do my absolute best," he said.

Webber admitted that his retirement was entirely down to his own mistake.

"Totally my fault," he said. "I got a wheel on the curb on the exit of Turn 12 and it was a very slow motion moment off the back of it. Totally my mistake. Today isn't my day.

"It was a very long one (slide), frustrating. I thought I had done enough but in the end it wasn't enough. The wall obviously was close and did some damage and then I wrecked Nico's race as well. It brings me back to them on points and we are all back together again so we go to the final two races."
