There's merits to using the game to make your life as a manager easier, I just don't see how a top FM player would make a good manager. So much more to managing, the pressures alone are far different and then you have the human side to it, managing 25 men from different backgrounds with different demands and issues. You might get a good idea of the tactical side to it, but the games have exploits where certain formations and training set ups get great results on that version of the game.
