"Sometimes you may deserve something, but you did not get it. So all you can do is to try it again. And this a little bit the same with my story in para-cycling. It has been a great season, but I know that it is possible to improve. So next year it will be another opportunity for me to try again. I know the clock is ticking, I am 48-years-old and I can’t go on forever, but I am very excited that, in spite of my age, I am absolutely convinced that I can keep myself at the same high level both in para-cycling and in motorsport."
