Despite winning four races so far this season, Haga sits 12 points behind the ultra-consistent Corser - but still has a realistic chance of defending his championship runner-up position from 2007, with title leader
Troy Bayliss now all but unstoppable.
"I'm relaxed and my battery is fully charged, so I'm looking forward to racing at
Donington Park," said Nori. "I always like to race at British circuits, like
Brands Hatch,
Silverstone and Donington and I always seem to have very supportive fans. I also usually have good results in British races.
"Last year at Donington race one was very strange because after the first few laps I did not seem to have any grip, and by the time I did I could only finish fourth. Race two was special because it was my first win of 2007 as the race was held in April last year. I had a very exciting battle with Max Biaggi and I have a good memory of the last corner of the final lap.
"This year I will try to get maximum points from each Donington race," he concluded.
Yamaha Italia will run a special livery on race day at Donington Park.
