1) Max out your charge/block slider and see if that gets you a better result. (it worked for me)

2) When backing down a defender, you cannot continously use the L stick to back him down or he'll flop thus resulting in a charge, block(slider maxed out) or no call. Use the R stick to make manuevers, and if going to use the L stick, don't press it directly at the defender for a lengthy time.

3) If you're trying to use the L stick to back the defender down and its not working, throw the ball bakc out of the post and start again.
