“Had I seen the drag curve for Jabulani prior to the 2010 World Cup in South Africa I would have been calling FIFA and Adidas saying please don’t use this ball,” Goff says. The fact that the Jabulani became unpredictable and beach-ball-like during these long passes really helped Spain win in 2010, Goff says. The Spanish team relied almost entirely on short precise passes, without long kicks that became unstable with the Jabulani ball. “That was the perfect example of a team that really fit the style of play for that ball,” Goff says.
“I kind of feel sympathy for the players and especially the goalkeepers that have to get used to a new ball,” Goff says. So far the Telstar 18 has received criticism from a few goalkeepers that played with it starting in November, unhappy with how it moves in the air and the way the surface feels. Goalkeepers, unlike every other player on the pitch, have to predict where the ball will go in order to block it, while also not having the freedom to run around the field to adjust as the ball flies. That means goalies often have the most complaints about a new design. “Every time there’s a World Cup and a new ball the goalkeepers complain, because they’ve been given a new ball,” says Goff.
In 1937, the regulation soccer ball put on a little weight, increasing from 13-15 ounces to 14-16 ounces. Soccer balls used to be made exclusively of leather. Not so these days! Current technologies have come up with leather-like synthetic materials that are softer, more lightweight, water-proof, and perform as well if not better than leather soccer balls. As for the look, early soccer balls were tan but difficult to see from the stands; although white leather-washed soccer balls are known to have been used. White soccer balls replaced their tan predecessors in the 1950s, and were composed of 18 panels. Black spots were added to allow soccer players to track the ball's swerve. Today's soccer balls come in an array of colorful designs and styles to suit every player.
It is also a good idea to clean your soccer ball after you have finished using it. Although regularly cleaning a soccer ball can be a time-consuming chore, it will extend the life of the ball’s cover. The grit, dirt, and debris that the ball can pick up on any pitch impacts the panels and stitching with every rotation. So clean it thoroughly and then allow it to dry for the best possible results.
The outer casing of a soccer ball is composed of panels made from synthetic materials, such as PVC, PU, or a combination, sewn or glued together. Soccer ball casings are rarely leather anymore, since leather tends to absorb moisture making the ball heavier and not perform as well. The number of panels or sections of the outer casing varies according to design. Most professional soccer balls are the 32-panel design. More panels mean a rounder and stabler ball, and a more accurate flight.
This time there is no stitching to attach the panels, but they are thermally bonded. This is the interesting part. First, we wanted to see how it performs in the air for a free kick. You will find a decent, predictable trajectory. Although when you are knuckling, the result mainly depends on your skill and the air direction, a ball plays a vital role as well to help your process of a successful knuckle shot.
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
