Author of The Weasel Way and presenter of United Soccer Coaches’ Reading the Game series Tony Nicalo:

In perceptual training, measurement does more than become something that is managed. It accelerates learning.

When a player knows you’ll count their scanning, they scan more. Measurement creates attention, and what players attend to is what gets stored.

The instrument becomes part of the training.

I wish coaches taught me how to scan when I was a kid.

It’s exactly how we implemented it with a World Cup-winning coach and his team.

For them, we also built a library of pause-and-quiz videos. We measure the speed and accuracy of the players’ responses to rate their reading ability.

But this is what they measure on the pitch, in training and matches.

This would be a great app idea local to a club, if it doesn’t exist already.
