Heard last night on radio that FIFA has apparently admitted that there may be something wrong with the ball but they won't do anything until after the WC. Makes me wonder who wrote this

Assuming that it is the most perfect ball I think that it is more affected by how it is delivered and atmospheric conditions such swirling winds, maybe even the air disturbances created by the players and their movements.
The perfection of the ball now shows up the previoulsy hidden imperfections of the players and environment.
