It's not a problem that exists outside online either, if the computer has the AI to not screw up, why can't user controlled teams?
The passing is my biggest problem online, So often a pass will go to the player wide left, rather than somebody at your immediate left, and touches are often heavy because of the lag, it's only slight but when you play offline you realise just how smooth it is compared to online.
And finally, the game its self runs nothing like football, games are dependant, quite literally on having 2 strikers up front, hit it to them, bypass the midfield, hold it up and wait for the other striker to make a move in behind, seriously dull.
