Not to mention when an attack breaks down (normally by the AI looking at your player and the ball to win it) your strikers will take an age to get back onside, meaning if you do win the ball back, you can't pass forwards quickly because they all slowly walk back onside.
Or when you try to breakaway from an AI corner, only to find your striker is doing his best to stay behind the last defender, despite being 10 yards in your own half because EA don't understand offside, or don't know how to program it so your players don't automatically assume they have to be behind defenders at all time (or simply don't care)
