U14 soccer drills should be simple enough to encourage creativity within the structure of the activity or drill.  The drills and activities withing the practice sessions should be focused around an overall concept or theme.  Focusing on technincal skills is still important and players need to start using their technical skills under pressure and with less time to make decisions.  Therefore, small sided games are great for this age level.  A good variation of small sided games will keep players engaged whereas to much repetition can lead to boredom for players at the U14 age level.  There is a nice example of a U14 soccer practice plan posted on our site that follows these principles.  Some important concepts at the U14 level include the first touch and movement away from the ball.  Again, small sided games can be a great tool to help drive home these concepts.
