Fremantle superstar Nat Fyfe says he was always destined to remain a Docker.

Despite being linked with St Kilda earlier in the season, the Brownlow medallist has signed a six year contract extension with Freo for a reported $7 milion.

Fyfe (pictured) says while he gave some thought to the prospect of a move, he never really considered it a possibility and hopes to remain a one club man for the rest of his career.
