In South Africa and across the world, it has become common for players to wear headphones before kick-off, especially upon arriving at the stadium, but you almost never see a coach doing the same, hence many, including Khune, were surprised by Nabi's actions.
Given that the experienced coach was photographed by the club's media department and the club has yet to comment, it seems unlikely that any punishment will be imposed on Nabi.
In addition, Chiefs have been inconsistent since the start of the season. They have currently garnered only 18 points from 13 matches, winning five times, drawing three, and losing five.
