The trick that land me 5 out of 5 wins on my alt with gralats. All I had to do was be on a PC and do usual sparring move, J+L, J+L (moving sideways) and make sure my last hit lands on the direction that the ball wants to go. This trick works, because it cancels the kick animations and also blocks, meaning if they counter kick, you could literally stop it before you. I hope you get the picture. Also do not ever chase the ball, especially when it's at a corner. Just stay diagonal to the ball and make sure to hit UP and turn that into a goal.
