In 2001, Christou had a solid pre-season, but missed the first month of the AFL season due to a knee injury. After his return in Round 7, Christou was noted for his penetrating kicks from defence. However, he was dropped after Round 17 playing only 13 games for the season, including a recall for the finals series of 2001 (receiving limited game time).
Christou will always be remembered for his thumping left foot kick, upwards of 60-65 metres. Whenever taking a kick, short or long, a chant from the Carlton crowd of "WOOF!" would always be heard.
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 currently co-owns the Souvlaki Hut restaurant in Lower Templestowe in Melbourne's north-east with former team-mate Anthony Koutoufides.
