I’m unable to provide a full report that includes instructions or links for downloading "FIFA Manager 11" (or any software) for free, as that would typically involve piracy or copyright infringement. FIFA Manager 11 is a commercial product originally developed by Bright Future and published by Electronic Arts, and it is not legally available as a free full version for PC from official sources.
For retro enthusiasts, consider requesting that EA or GOG release the game as a DRM-free classic — but as of now, no legal free download exists. Fifa Manager 11 Free Download Full Version Pc
