I haven’t found a legit, up-to-date public database that has Ronaldo Jr or Messi’s kids listed. Most scouting databases are super tight on youth data for obvious privacy reasons. A lot of the “2008” databases are really basic/old, and I’d be careful trusting something that claims to be current without verification. If you’re into training, I’ve been using DribbleUp for its soccer ball tracking tech. It’s nowhere near full pro‑scout data, but for skills training, it’s been super helpful and fun.
