The team managers were useless. They didn't do their jobs properly and blamed each other when something didn't get done, and no one was held accountable as a result. These team managers were drinking every day at the pub and some were even playing golf throughout the tournament. They treated it like a holiday.
The players felt this was a massive distraction and ruined their world cup. However, they feel the coaches did great and want to make sure their praise is heard.
Lastly, they are suspicious that the team's money was being used to fund their daily binge drinking sessions, and to pay for better hotel rooms for the managers who weren't even doing their job.
