I bought Football Manager 2010 when it was released and i have tried and tried to get used to it, but i just can't i find it too hard to work too much buttons and the layout is completely complicated. So in my personal opinion i will be sticking with 2009.
I just finished a whole season with arsenal i finished first and had a win streak of 23 games without buying any players all season arsenals squad is amazing i think you made to many signings.
