Ask yourself first if SOCCER will be the life you have planned out for your child? Then ask your child what he/she wants to become in life? At less than 10 years old, I don't think they have a clue....It makes no sense putting your child in CLUB for any sport at less than 10 years old. They're going to need to be exposed to other sports. Not only to experience other sports, but to make them a more well rounded athlete in the process.
1. Some kids know early on that's what they want to do. I tried everything possible to get my kid out of club soccer. At age 10, he had a coach tell him he had no business playing soccer and no future in it (cut him right after losing a playoff game). His OT and school counselors even told him to get out. He had a teammate scream at him once in the middle of a game to go back to AYSO. Tried to get him into martial arts, tennis, equestrian, swimming, lacrosse and water polo. Wouldn't take but the kid (with a lot of hard work) managed to get competent, and then good and move up the ranks.
2. The incentives in youth sport are all messed up by college recruiting and scholarship. It's caused an arms race where kids are specializing in sports earlier and earlier because in order to keep up with the others, you have to do your 1000 touches a day. It used to be just a decade ago that the United Soccer Coaches wouldn't recommend kids go full time goalkeeper til at least age 12. Reputable goalkeeper coaches wouldn't take them until age 10. Now days, you see full time goalkeepers at the camps age 7 or 8, and 8 year old keepers expected to perform advanced moves like diving, 1v1 and coming out for crosses when they should be spending their first year of training on learning safety and the how to catch. As a result, 11 is fairly old now to be jumping into the club soccer scene, at least in SoCal. It's not just limited to sports BTW. You see it in honors math (CLC or Kumon anyone?), spelling, the arts, music and dance.
3. If they aren't sure about other sports, it's a great idea to expose them to a bunch of sports before they commit to one. Unfortunately, even for lower level flight 3/bronze teams, it's a year long commitment making that difficult. But because of the reality of sports specialization, while in the ideal it might be great to make them well rounded athletes, as far as the colleges are concerned, they don't really care. They recruit for particular sports and being "well rounded" (in sports or otherwise) only checks a box. You don't get "credit" if you already play a sport for playing another. It's sad, but the significance of a "well rounded" athlete is fading in our society.
