These games are ones I've found to be useful in training players. The information I am posting as been learned at various coaching schools and camps I have attended. The USSF Coaching School laid the foundation of my training and is heartily recommended. The Maryland State Youth Soccer Association conducts International Soccer Coaching courses every summer. Contact them at 410-987-MSYS and ask for information. Past sessions have included coaches from the Irish FA, KNVB/Royal Dutch FA, the Czech Republik FA and Brazil. The information learned at these sessions as been invaluable in my development as a trainer of young players.
To be really good as a coach, don't be afraid to ask questions. If a coach in your area is successful, watch and find out why.
