Yep, I did a comment of that some months ago, is a "error" of the game. In penalties or fouls who recive the foul is who assist, like in a corner if a ST score, who pick the corner is who assist...

One thing that now I don't remember is, if in a foul for example, the ST or another just touch the ball to do the goal (or with the head) and it appears like assistance... ¿?

Too in some other moments when a player recive a passing can have the consideration of assistance but... now I'm not sure about what do this game... LOL

Too is difficult see a hand... or a moment in what to do a "cession" inside the area... but well, .. in general terms I thing that this is the most interesting game we can play in facebook, we can no have all
