Koala blocks Mark Webber's way, Formula One star tweets

Days after his bid for victory in Malaysia was thwarted by a gung-ho Sebastian Vettel, Mark Webber has found himself halted again - but this time by a koala.

"Stopped in my tracks. He's on a mission the little fella," Webber posted on his official Twitter feed, alongside a photo he took of the marsupial crossing the road in front of him.

The message provoked some ironic responses from Webber's fans - still smarting after last Sunday's incident. "Good man, Vettel would have hit the other pedal (by mistake of course)," wrote one Webber supporter. Another commented: "At least he didn't pass you."

Webber has returned to his native Australia to cool off after the Sepang storm with Vettel ahead of next month's grand prix in Shanghai.
