As of my last update, there is no widely recognized soccer player named Julius Simon associated with the Slovak team Dunajská Streda. It's possible that Julius Simon could be a lesser-known player or a youth prospect who hasn't gained significant media attention.

FK DAC 1904 Dunajská Streda is a professional Slovak football club based in Dunajská Streda. The club is well-regarded in Slovak football and often competes in the country's top league, the Fortuna Liga.

If you are looking for specific information about a player who might not be widely known, it is best to check the club’s official website or local Slovak sports news outlets for the most accurate and up-to-date information.
