How do you do a shot with a bit of curve on it? I can't seem to do that on the PC. Also I don't know how to save a penalty with the goalkeeper. Well, in particularly, what do I push to make him dive one way or another?
Use the left and right sticks to curl and dip after your release the shoot button on your controller. If you are using your keyboard and not playing a FPS, I don't know what to tell you.
To save a penalty use the right stick on your controller in the direction you want to leap in.
