Football Manager 2010 has shown improvements over 2009 but there hasn't been a major overhaul. These baby steps were to be expected and the old saying "if it ain't broke, don't fix it" springs to mind. The basic 3D match engine is still far from awe inspiring but it does tweak a few issues which plagued the previous incarnation.
This remains the greatest Football management series on the market. There really is no competition.
