After many games and much testing I have concluded that the most challenging difficulty this year is 'Superstar'. The computer really makes you pay for mistakes (badly placed passes and miss time tackles). The GK`s make less mistakes on this level as well. They are a lot more consistent, though I won`t be surprised if a see a howler once in a while. If its in the game, its in the game. However, 'Top Player' is challenging and fun as well.
