10. Miguel Herrera
Mexico is one of soccer’s biggest underachievers. The Central American nation adores the sport but fails on an international level. It looked like Herrera was on course to change their fortunes. His passionate sideline antics at the 2014 World Cup attracted global attention. Meanwhile, Mexico visibly improved under his tenure.
But sometimes passion can be a dangerous attribute. Herrera discovered this the hard way after losing control on the sideline. He became embroiled in a dispute with a reporter. It ended with the coach physically assaulting the media member. As a result, Mexico fired its manager. It was the wackiest way for him to leave, but probably not that surprising.
