Despite the similarities with the Brazuca, the few differences between this ball and what players have gotten used to over the last four years will have an impact on play, says Firoz Alam, an aerodynamics engineer at the Royal Melbourne Institute of Technology in Australia, who has also performed wind tunnel tests on the Telstar 18. “When the player is making a short pass, they have to push a little harder, because at less then 60 kilometers per hour [or 37 miles per hour]it has more flight resistance than the Brazuca,” says Alam. The mid-range passes and corner kicks that gave the Jabulani so much trouble have been resolved. Compared to the Brazuca, the Telstar 18 is also more aerodynamically efficient in the 40-50 mile an hour range, so Alam says players will actually have to kick a little softer or they’re likely to overshoot. Over 55 miles an hour the two balls will feel very similar.
Match balls are constructed specifically for competition and the sport's high-level training. These balls feature higher quality materials and must conform to regulation standards of your league. Training and recreational soccer balls are designed to handle extended use on a variety of playing surfaces, often featuring a PVA casing for enhanced durability.

This 12-oz. ball works for players between 8 and 12 years old and has a circumference of 26 inches, larger than a size 3 and smaller than the size 5. This age group tends to play on a field of about 30 to 50 yards, writes Deborah W. Crisfield in "The Everything Kids' Soccer Book," with a goal size of around 6 feet high and 18 feet long. Again, the scale for the U12s falls between that of the U8s and that of the older age brackets for the No. 4 ball and the game as a whole. Some leagues may limit the No. 4 ball to U10s instead of U12s, so check league rules before making a purchase. 
These soccer balls are exact replicas of the finale game balls, right on down to the specific design details that can be found on the ball. If you’re looking for a durable, reliable ball that can help players replicated the feeling of playing the game at home, then the Top Training Series by Adidas is one of the best options to consider today. Each ball is guaranteed to pass FIFA tests for weight, circumference, rebound, and water absorption. It is the closest you can get in the entry-level categories for a soccer ball to the match ball experience. https://www.youtube.com/watch?v=3OKagE2ZIRA
