1 v 1 is one the most challenging factors for keepers (in my opinion). I love to see keepers defending their area as truly warriors. However, all these moves and attacks are quite dangerous if your keeper hasn’t been trained properly on this technique. The idea is to defend your goal in the safest manner possible.
I don’t think 1 v 1 will end up most of the times in a goal, as I read in one post above. In my experience with my son, he handles 1 v 1 so good, shutting down 80% of the plays with no problems.
I agree that majority of coaches have no clue on how to develop a keeper, unless your coach is a keeper (as mine), but I will say, encourage your son or daughter to get out the goal area and explore possible alternatives to improve.
I’ll share a highlight video of my son from last season. This 11 years old kid made a huge impact on his team success
Has he been injured yet?
