Mark Bosnich’s career collapsed after he failed a drugs test at Chelsea in September 2002. The club dismissed him, and football authorities imposed a nine-month ban after the test detected cocaine. The suspension destroyed a possible move to Bolton Wanderers and effectively ended the goalkeeper’s career at the highest level just as he was attempting to recover from injuries and a prolonged loss of form at Chelsea. The episode was especially damaging because Bosnich had once been regarded as one of the Premier League’s best goalkeepers and had earned a major contract reportedly worth about A$130,000 per week at Chelsea.
Bosnich later acknowledged that the failed test was part of a far deeper addiction. During roughly six years away from professional football, he became increasingly isolated, spending as much as $5,000 a week on cocaine and claiming that his consumption reached as much as 10 grams per day at his lowest point. In one alarming incident, he nearly shot his father with an air rifle after mistaking him for an intruder; his father subsequently helped persuade him to quit. With encouragement from former Chelsea teammate Ed de Goey, Bosnich began training again in 2007, lost approximately 15 kilograms, and eventually returned to professional football in Australia with the Central Coast Mariners in 2008. He later described the addiction and exile as the darkest period of his life, while the failed test remained the defining scandal of his career.
