Mark Webber admitted that a strong start to the Korean Grand Prix will now be vital after earning his place at the head of the field in qualifying.

The Red Bull man edged out team-mate Sebastian Vettel to pole in Yeongam after Vettel had earlier led the way through the opening two phases of the session.

It gave the Australian his second pole position of the year by less than a tenth of a second, and he admitted a strong start to the race would now be vital to ensure he kept his advantage,

"It was a tight session for all of us," he said. "I think as the session unfolded, people were having different balance issues on different tyre compounds. I was happy with my lap there, it was solid and it's good to get pole. It's a great place to start the race from.

"I'm looking to get off the first corner very well, that's important as there are two long straights after that."

The Australian added that the result was particularly pleasing given that a technical issue had limited his running in the earlier final practice session.

"We didn't get to run anywhere near as much as we would have liked to in P3, so our information on the option was limited," he said. "So there was a bit of catch-up going on for sure. After my first run on the option in Q2, I didn't have the best sector two and three witj some balance issues and also some other things. That's what we focused on in Q3, and got the job done."

As well as being cause for celebration on a personal level, the pole position was also one to celebrate for engine supplier Renault, who secured top spot in qualifying for the 200th time in F1,

"Today is an important day," Renault's Cyril Dumont admitted. "Not only have we got the front row of the grid again, but we have also scored our 200th pole position with the Renault engine.

"We started with Jean-Pierre Jabouille in 1979 and 500 races later we have achieved more than 40 percent of pole positions from all our Formula One qualifying sessions. That's a very strong score for Renault. Among these 200 pole positions, more than 40 were achieved with Red Bull Racing and our two drivers, Mark and Sebastian.

"I would like to thank everyone at Red Bull, both drivers and everyone working at our factory at Renault."
