Im not concerned about goalies that much... Yeah, they make mistakes, but they arent that horrible. (I play only offline, no interest in online). But the one thing I noticed is that I started playing on superstar right from the beginning and sometimes its just too easy. Especially when you dont sprint, but try to avoid AI defenders by just running on a regular speed and moving your player with arrows. I did "Messi" with Diego Costa, with Ayoze Perez, with Lacazette and few other players, meaning I just literally outplayed 3-4 defenders, went into box without holding sprint, just moving on a regular speed (as mentioned) and then just scored goal. It looked so easy and I could do that again and again. It would be alright if it was on a lower level, but now on a superstar! By the way, im playing on ps3, but I suppose there is lots of similarity in terms of gameplay, not visuals between current and old gen, so... Maybe I will try to play on a game speed turned to -1, maybe this will prevent outplaying every defence, without even trying.
Update: Nah, played on -1 speed, but did the same thing with Embolo from Basel against whole Wolfsburg defence. Literally walked in theyr box for some time, no one could steal ball from me, there were lots of free space, because if I`ve beat one defender, others would pull away and only after some time come to help. Interesting.
