This can be used as a great option for goalkeeper training as well. Why? Look, you can hardly see the lines on this ball, hence you won’t be able to guess the direction by only seeing the spin of the ball. That means as a goalkeeper you will have to give full concentration to detect the direction of the sliding balls. This is obviously helpful if you are a goalkeeper, and looking for a sliding challenge.
With the increased seam length, Goff says there was actually a risk that this ball would be too rough. “Very little changes in those textures can have noticeable aerodynamic effects,” he says. The fact that the Telstar 18 has almost the same drag curve as the Brazuca, with aerodynamic properties changing at about the same speeds, is impressive. “It has to be an engineering and technical challenge,” he says.
“We found that the grooves and pimples on the Telstar 18 ball are very orderly and a little bit flat,” says Alam. The pimples that texture the surface of the ball are not as raised as on the Brazuca, and the seams are narrower and shallower than they have been in the past. All of the elements of the ball—the increased seam length, the more regular pimple pattern, orderly pimple and seam shape—add up to a more symmetrical, balanced ball, Alam says. “We expect this ball to have better flight stability.” And since all 11 stadiums in Russia are at the same altitude, Alam says the ball should play the same way across all matches.
Soccer — or football as it's known around the world — is arguably the most loved sport on Earth. Although Americans still aren't as enamored of the sport as the rest of the world is, teams around the country are stealing hearts and minds, and Americans are getting into the game. For years, soccer has been a sport played by kids, college students, and ex-pats, but it's now being cheered in stadiums and watched on national TV. https://www.youtube.com/watch?v=DGp37du0xbQ
