I doubt he was on your average neo-pro salary given he was the reigning u23 world champion when he turned pro. But I think his performances last season justified a significant salary increase.
That shows that he was on neo-pro wages when he was a neo-pro (in 2019). The least he would have earned in 2020 is €39,068 but I suspect quite a bit more. Still wouldn't have been a Rad Millionaer though!
