Neh, it's something that was in an earlier version, but that they didn't put in in this one. However the code is still there, so it's possible to bring it out. It's stats on how many minutes player x have played, team goals for and against, penalty score percentage, and lots of other stuff I've forgot.
I don't have it anymore now. Had to reinstall FM due to me clicking on the titlebar in the manager history. That screwed it over, and it was impossible to default it. This got to me, and the only way was to reinstall. Weird.
I'm still on Aurora 2006 though. Top stuff. The default looks dead now
