Manchester United brought Bosnich to England in 1989, but a lack of first-team opportunities and a failed attempt to secure a work visa, saw him return to Australia. A year later, Aston Villa brought him back to England and he established himself as one of the best goalkeepers in the Premier League during the 1990s. Manchester United re-signed him in 1999 as a replacement for the departing Peter Schmeichel, but injuries and a lack of first-team opportunities led to a decline in form. He left Manchester United for Chelsea in 2001, where he again struggled to find a regular place in the starting line-up and continued to battle with injuries. In September 2002, he was released by Chelsea and banned from football for nine months after testing positive for cocaine.
