O'Leary Manager 2000

O'Leary Manager 2000 is a football player-manager game released in 2000 for the Game Boy Color. The player can choose whether they want to focus on the management side of football, play the matches themselves on the game's 2D match engine, or combine the two features for a more in-depth experience.

It is endorsed by Irish football manager David O'Leary, who was managing Leeds United A.F.C. at the time of the game's release.
