I'm working with one of my program's keepers (15 yo). I have some drills on various aspects of goalkeeping but one thing we both want him to particularly work on is his hands. He's good at blocking shots but he often takes two touches to catch balls that other keepers would catch cleanly. Basically, he uses his palms to block the ball and take the force out of the shot and then either catches the ball in the air or after it bounces. Most of the time this ends ok, but obviously if he's in a crowd or if there's a striker or wet ground, it can be problematic. This is a habit he recognizes and that we both want him to break. Do you guys have any suggestions for drills we could do that would specifically on softening his hands? Also, he's going on vacation next week so I won't be working with him for a while and he wants drills that he can do by himself. Any ideas for stuff he could do (doesn't have to be related to the above) by himself, aside from sitting in front of a wall and tossing/catching?
