Plyaer updates, which are released every week, make no fundamental difference to how the game plays. If you go on
http://sofifa.com you can see each week's updates and how each player that has been edited is now different. In rare cases, for example Liverpool, when many players were listed in the wrong position, that team may play different in your CM due to using other players in their starting line up (I also had Liverpool fighting to avoid relegation in my CM, which was annoying)
If an update has changed team tactics, then it can have an impact on how those specific teams play. But I don't think they would update ALL the teams in an update. Even then, the game won't play different because of a roster update.
- Are you crossing from the wings or from the centre of the field?
- Are you pointing with the left stick towards where you want to cross or just pressing L2+cross?
- Are you holding L2 first (for 0.5 a second maybe?) and then pressing cross or are you pressing them almost simultaneously?
- Are you using Automatic, Semi or Manual crossing in your controller settings?
