These young players are very eager to learn. As a coach you should take advantage of the opportunity and build on the basic technical and tactical concepts the players have worked on already. The game itself should be central to all technical training. Players in this age group start to move from how (technique) to when, where, with whom and against whom (skills-tactics). The technical development of the players is still the #1 priority. Continue to build the player before the team.
