Dominate the 1 v 1!   

Keep everything small sided,  1 v 1, 2v2, 3v2, etc etc!   This will maximise the touches your players get on the ball, thus maximising passes, control, shots, tackles, dribbles!    Using small games based activities is much more engaging and beneficial than the old school 'wait your turn line drills'!  

Keep everything focused on the individual and technical information, like passing, dribbling!  Things like positions and positioning can come much further down the line.  At that age, your job is to build the foundations. 

Grow a love for the game within your players!
