The zidane spin is one of the hardest spins that you could teach a child which I have found to be difficult. How would you be able to correclty teach this spin
It shouldn't be taught a very young (skill) level.
I say skill level not age because players master skills at different ages.
One example...
If you said it should be taught to a 14 year old, that is the age Freddie signed with the MLS!!!!
On the other hand there are plenty of 14 year olds that still toe kick.
It is an advanced move and moves are taught best when they are broken down step by step in slow motion. The Coerver tapes are great for learning moves.
