As of my last update in October 2023, I don't have specific information about any U23 players who have been announced with titles. The World Cup qualifiers and the upcoming tournament can be quite dynamic, and player announcements often occur closer to the event.

If you're looking for recent updates on U23 players, it would be best to check official football news sources such as:

- FIFA's official website (fifa.com)

- Major league soccer websites (e.g., MLS, La Liga)

- International football associations' websites (e.g., CONMEBOL, UEFA)

- Sports news outlets

These platforms typically provide detailed reports on new signings, transfers, and player performances at various levels of the game, including U23 competitions.

For more up-to-date information, consider following these resources or subscribing to sports newsletters that cover international football. If there is any specific team or player you are interested in, feel free to let me know, and I can help guide you further!
