I'm going to warn you if you buy this game you're in for a world of frustration.
Firstly i have to say this might possibly be the worst AI of any Fifa game ever and i have played a lot of them, not just the AI of your team but the AI of the computer is awful as well. You'll find yourself doing everything as your defenders just idly watch the opposing team run circles around them (never putting a foot in or attempting to close down even when you select pressure). You'll enjoy the opposing AI score every shot they have (because they don't shoot until they're at most 3 meters from the goal).
I drew 3-3 with Wolfsburg on world class here's the stats;
Possesion: Me 62%, WB 38%
Shots: Me 19, WB 3
Shots on target: Me: 12 WB: 3
Goals: Me 3, WB 3
See any pattern?
That's just one of many match stats i have had where every computer shot is a goal, you'll notice every shot they have is on target that's because they are so close they literally cannot miss.
Every team on high difficulties play like they're Barcelona trying to walk it into the net it is incredibly frustrating, i have not (not once) seen the AI shoot from outside the area. I thought this was supposed to be more "real" EA? every goal the AI scores is exactly the same, never shooting from outside the box, never crossing. It's clearly obvious that when you go up in difficulty it nerfs your team and makes the opponents team better(stronger, faster). I for one do not believe there is scripting in this game but i know there is momentum, take the lead on world class or legendary and see what happens, the other team suddenly seem like they have taken steroids...
I'm done with this game, i had a little fun with it but it has just pissed me off lately. I would only recommend this game for people playing online because the offline experience is abysmal and i don't use that word lightly.
