Cheers for the tricks m8, but just at to add that heel dash can be done left or right on PS3 anyway, but it does have to be @ a 90 degree angle. It's timing more than anythin, but once yu get it it's easy (I'll upload vids when I'm back on broadband.
Tip: Let the ball run infront of you a lil bit ie loose the direction button for a sec, not long enough for the player to stop, but long enough to watch him catch upto the ball again. when he does do a 90 degree direction (left or right) and press R1 (right bumper for 360 users) @ exactly the same time.
Oh and the nutmeg is easier than it sounds too. Hold R2 when your stationary and quickly press back and forward and thats it, trick done.
