Christou played for the Carlton Football Club and along with Anthony Koutoufides was a popular figure as a Greek Australian.
In 2001, Christou had a solid pre-season, but missed the first month of the AFL season due to a knee injury.
Christou was the second Carlton player to receive this chant, after Val Perovic (another long, left-footed defender) during the 1980s.
There was talk of Christou trying out as a punter for the National Football League in early 2003, a three-man crew from a US club (the identity of which Christou refused to reveal) spent two weeks in Melbourne putting him through a series of stringent tests however no signing resulted.
He co-owned the Souvlaki Hut restaurant in Templestowe Lower in Melbourne's north-east with former Carlton teammate Anthony Koutoufides, until its closure in early 2011.
