FIFA 12 introduces a new tactical defending feature, but I can't really seem to get the hang of it.
If you shield someone (standard button A), your player always stays 1 meter in front of him, but never actually attacks unless the opponent runs into you.
The actual tackle (standard button B) only works for me if I run beside him, otherwise the opponent just makes a sidestep and is through.
Calling a second player with R1 also just gets him to shield, not to attack.
Are there any tips for properly defending with the new mode, especially against the higher AI levels?
I know you can turn it back to the old mode, but I'd rather learn how to use this.
