Playing with my brother, same console, we seem to have a few items that we continuously have a problem with that should just absolutely not happen.
First issue, biggest issue. Passing. I haven't had this be an issue too much in 1 player mode, but when playing with two people (different teams), it seems it's very common for you to attempt a pass in one direction, only to have the ball go in a completely different direction. For example, trying to pass forward and having it go out to the wing, or passing into the center when near the goal and it going backwards towards midfield. This has been the cause of both missed scoring opportunities and weak goals given up when it happens in the back or off counter attacks that should have never happened. There's just no excuse for this happening. It seems to happen on a fairly frequent basis, maybe 5-10 times a game.
Poor goalie AI. I know goalies are supposed to be improved, but there's no excuse for a ball to be floated into the 6 yard box and I have to manually tell my keeper to grab it. What's worse is they hesitate a second before making a move if you manually tell them to come out. If a goalie can definitely get to a ball in the air I shouldn't have to tell them to attack it. I'd also like to be able to see goalies move on the ground and crawl or reach for a ball if they are already on the ground. Right now if they go to the ground and the ball is near them they just stand right back up. Also, lack of control when choosing who to pass to off a goal kick or throw to when the goalie has possession. It's a crap shoot I'm sure we've all let up a few goals because it doesn't pass who we want to (the logical choice).
Poor offensive AI. Players generally don't move off the ball all that well. They're ok if you are pushing forward, but if not you are generally out of luck. Players don't make runs unless you are actually advancing the ball. Sometimes I just want to stop and hold it for a second to maintain my passing angle, but if I stop pressing up so does the player making the run. Other times my outside back might be bringing it up the wing from the back with none of the other team around. For some reason my outside midfielder on that side decides they need to check back to him and get within 5 yards before he takes off up the field, at which time he's generally drawn a defender to my back and taken away any passing angles. Computer players never overlap either. If I hold the ball or cut inside I'd like to see the offensive players adjust to what I'm doing. Move to the open space.
2 defensive AI complaints. The first is computer controlled players slide tackling players on the wings when there is no reason to. They'll be running neck and neck and then my computer controlled character will just wipe him out for no reason. The second complaint is computer controlled characters going to where the ball is and not where it will be. For example, if there's a ball in the air, and the other team is clearly going to win it and take off up the field the defender doesn't drop back, take away angles, and contain, they just run to where the ball is supposed to hit the ground and then the offensive player blows right by them because the defender was never going to get there in time and just took themselves out of defensive possession. This also commonly happens with defenders coming over to help on a guy breaking down the wing. They don't cut off angles, they just go straight at the guy. This is even more frustrating when your defender is slower then the offensive player because he never has a chance of getting to the man with the ball.
One more defensive complaint I just remembered. It most often occurs on corners. Defensive players will have the ball coming directly at them and then just run up the field leaving an offensive player wide open to put it in the net. I've even had this happen when I've been controlling the player. There is no reason this should ever happen.
These seem to be the most egregious problems I've noticed playing and really go a long way to ruining the fun. If you lose the game you want to feel like it's because you messed up or the other team just made a great play, not because your AI teammates did something stupid or because of broken controls that start spraying passes in every direction except for the one you actually want the ball to go.
