During this time, he met British model Sophie Anderton and moved in together. The two had a tumultuous two year relationship which ended due to allegations of drug and physical abuse. Bosnich soon left Chelsea and did not return to football until 2007 as a result of drug use.
Bosnich has admitted that much of his cocaine problem was due to his relationship with British model Sophie Anderton. He does not regret his actions however, crediting them with being able to help someone in need. "All I did was fall in love with someone and care about them deeply and I put them ahead of everything and so be it... As Martin Luther King said, `life is not worth living unless you find something worth dying for ... And at that time, for me, that person was more important than football.". His addiction soon worsened; he later said "There was a stage where I got up to 10 grams a day when I was really down in the dumps."
Anderton struggled with her drug abuse years after. She unlike Bosnich has maintained a high profile in the media by competing in I`m a Celebrity Get Me Out of Here and Celebrity Love Island.
