Yvan Muller had another stunning this weekend at WTCC's first visit to the Moscow Raceway in Russia. He got pole position, victory in race one - taking his win tally to four this season - and second in race two.

The Frenchman now has a dominant 113 point lead over his nearest rival Gabriele Tarquini at the half-way point of the 2013 WTCC season, and is looking nigh-on unstoppable to take a record fourth title.

Despite a red flag early in race one with the restart further delayed after the recovery vehicle itself ironically broke down trying to clear up the wreckage from a lap one incident, Muller held his nerve to win by just under four tenths from "Flying Dutchman" Tom Coronel, who kept the pressure on the RML Chevrolet driver all the way to the line right from the get-go.

The former British champion hailed a "great weekend," but still knows all too well that he has to "stay focussed" until he has secured the title.

"Of course I'm very pleased. It was a great weekend; pole position, race one victory and then a second place. I am especially happy for our partner, Lukoil, as this is their home race.

"I don't think the red flag in race one helped me, because it came very early in the race. I was surprised because my tyres remained at a good performance level for longer than I had expected. Only in the last three laps did I have to fight hard to keep Coronel behind.

"I did not expect to have nearly twice the points of my competitors after the first half of the season, it is quite amazing. Now we have to stay focused and keep like this until the end of the season."

Yvan Muller will no doubt hope to increase his championship lead at the next round of the championship in three weekend's time at the Portimao circuit in Portugal.
