Notts County have confirmed Sol Campbell has left the club.
County chief executive Peter Trembling told the club's website: "While we are disappointed that Sol felt that he could not adjust to the long-term nature of the project under way at Notts County, we obviously wish him the best with the remainder of his career and hope that he is able to obtain a place where he can play at international level ahead of the 2010 World Cup."
Trembling continued: "The investment project is on track; we have brought in a lot of new players and resources into the club, but obviously this is a five-year project, not a five-week one." Campbell agreed a five-year deal at Meadow Lane in August for a reported £40,000 a week after leaving Portsmouth at the end of last season.
