Cameroon's World Cup promised acrimony the moment players refused to travel to Brazil over a bonus row, and during their 4-0 thrashing at the hands of Croatia left-back Benoit Assou-Ekotto headbutted teammate Benjamin Moukandjo.
Alex Song had earlier been sent off for elbowing Mario Mandžukić, and in the heat of Manaus' Arena Amazônia the violence continued. Assou-Ekotto turned on Moukandjo and the pair had to be separated by Pierre Webó.
