WATCH exclusive footage of Melbourne’s Tom McDonald wearing a specially designed camera during Thursday’s main training session at AAMI Park.

Sports Performance Director Neil Craig said the footage was used as a coaching tool to improve the players’ on-field communication.

“We are interested in decision-making and instructional communication and this technology gives us the opportunity to monitor that,” he said.

“As a club we have a new playing group and a new coaching group and we will continue to trial innovative ideas to improve our club.

“It’s important for our football club to expose our players to every avenue to help them be the best they can possibly be.”

The camera is housed within a specially designed pair of sunglasses.
