I am looking to go through the basics with my son, I watched grass roots goal keeper traing DVD (on YouTube) thought it was great, and then I put together first traing session; standing position, catching by scoop, catching higher, the k stance, diving left/ right from knee. Son enjoyed it, but was wondering if there were any intro to gk coaching showing very basics? Or any advice of drills would be greatly appreciated.

Guys, what would you say are the TOP 3 skills and or techniques as goalkeeper must master to become a semi or professional goalkeeper ?
