I am relatively new at this. This is my third season as a coach. I have 5 total on an 8 man roster returning from last fall. We are U-8 playing 5 on 5 - (goalie plus four).
On my roster, one has a club foot and is playing an almost exclusive goalie position. We tried defender but he keeps getting beat. He has turned into a fairly good goalie.
The others vary in speed and ability.
Next fall we move up to 7 on 7, but this spring we are 0-2 and facing 6 games in the next five weeks. Any help would be appreciated.
My best advice to you is to Defend Deep, keep 2 Fullbacks tight in front of your goal and control the center of the field (force or encourage the opponent to go toward the sideline). See "Defending Deep Basics" on Premium for more tips.
AT U-8, it's mainly about natural athletic ability. You can't expect too much. Focus on the basic skills and you will see improvement.
Good luck. Please let me know what helps.
