Vauxhall duo set for title showdown

The Frenchman has a 29-point lead over his nearest rival, team-mate James Thompson, with just 35 points up for grabs in the two races at Oulton Park.

"I'm just going to try and do the same as always - score points," said Muller. "Oulton is usually a bit better for me than Donington Park, I like the circuit, so hopefully I can be lucky. Last year I was first and then tenth in the second race after some problems. We will just have to wait and see what happens this year; only time will tell."

Thompson overcame Muller in a final round showdown to win the championship last season and insists he will push his team-mate all the way, despite the substantial points gap.

"I'm not going to make it easy for Yvan, " said Thompson, "he is close but I'm going to make him work for it. There is still a chance that I could do it, so I'll be fighting all the way. If I look at it selfishly I need Yvan to have a disastrous race, but that wouldn't be good for Yvan or the team. He made it very hard for me last year and I intend to do the same for him."
