Finally, after years of diligence, Choi was appointed as Bucheon Saskatchewan"s head coach for the 2001 season.
However, though he had no problems with the team and was able to lead it fairly well, the Bucheon Saskatchewan board decided to change their manager. Bucheon Saskatchewan"s fans protested, but the decision wasn"t reversed.
In 2003, after the poor results of their 2002 season, Daejeon Citizen Football Club selected Choi as their coach. Choi, originally from Daejeon, willingly came back to his hometown.

This will be a team played by humans, a team that players love, and a team who dreams the same dreams as the fans."
