Whether it was a size 3, 4, or 5, we found that the Adidas Starlancer performed as it should. This allows beginning players at any age to begin getting a feel for what it is like to have the ball at their feet. There are two color options that come with the Starlancer as well and each performs as it should. For normal passing, crossing, and shooting drills, we found this soccer ball to be true to form. The machine stitching is strong and offers a fairly long lasting performance.
Everything becomes scaled down for smaller soccer players compared to the adult game. Kids play on small fields nowhere near the size of a full regulation field 100 or more yards long, with as few as three players compared to 11 for grownups. Even in a league, parents may serve as referees, games may last only 20 minutes and scores more than likely won't be kept. In keeping with this small world, kids' soccer balls are also smaller.
2010 Jabulani Adidas This ball has 8 panels. A special variant was used for the final match, the gold Jo'bulani (picture on the left), which was named after "Jo'burg", a standard South African nickname for Johannesburg, site of the final game. The ball was notable for the controversy it attracted, with players and fans contending that its aerodynamics were unusually unpredictable. 
On the other hand, replicas (sometimes called training balls or gliders) are designed to be just like the official match balls but are much cheaper. Their panels are often stitched rather than thermally-bonded and are made of a different material. However, they’re not necessarily less durable than official match balls. So, they’re the recommended option for most players. https://www.youtube.com/watch?v=j2Xn84L3Kcs
