The arm pump problem was clear today. For more or less 10 laps I could hold Jack Miller at bay by one second, but then I suddenly had no more feeling in my right arm. We were in a great position to win here. I could have even gone a bit faster. Our strong point of riding on the used tyre was finally not necessary, because I didn't have any power left in my arm. I will take my time today to think over the situation and try to make the best decision about how to deal with arm pump as soon as possible. My home Grand Prix is coming up next, and I want to be fit there, that's important to me. I know that the bike works well there and that I will perform well. I want to solve this problem as fast as possible, but in the best way.
