As a response to the problems with the balls in the 1962 FIFA World Cup, Adidas created the Adidas Santiago – this led to Adidas winning the contract to supply the match balls for all official FIFA and UEFA matches, which they have held since the 1970s, and also for the Olympic Games. They also supply the ball for the UEFA Champions League which is called the Adidas Finale.
A ball is just a ball, right? Well, it’s not quite that simple any more. Some important things to consider are what the ball is constructed of, what material is used for the lining or bladder and, to state the obvious, the size of ball you require, which will depend on the ages of the players and the ball’s intended use, be it for training or match games.
Huge fan of Bend-It, I would not consider buying any other brand of ball. I have 4 or 5 different styles that have been used and abused during club training and off-season indoor games. It's fun watching another coach pick it out of a crowd of balls to check the brand. I've even had a pro player pick this ball out of a crowd to use in group training sessions (Go STL FC!!)
The most modern feature is an embedded NFC chip, which is found on the top of the ball. If you download a free app on iOS or Android, you can personally interact with the ball's exclusive content and location-specific challenges. You'll also be able to participate and enter competitions and World Cup-related challenges. Of course, you can record and upload your experiences for social media posterity.
This is a decision that your coach or manager get to decide for you if you are part of a team. Your own ball is one thing that you have control on. However, when it comes to what the team should play with, it is the manager’s job to pick which ball is the best, and what is appropriate for the team for training. Coaches usually stick to training match balls as they give the illusion of actual match balls.
