I've got a few bucks in my pocket that bets you might be here for the wrong reason. Most coaches find this article because they want the best formation to win soccer games. What they should be looking for is the best formations to teach the game. Surprisingly, they are often one in the same.
There have been many arguments (heightened debates, we'll call them) as to which formations are the best for youth soccer players. What I am going to tell you has been proven time and time again and is now endorsed by many national soccer clubs and organizations. This format also basis itself in the K.I.S.S. formula (Keep It Simple Soccer) and "transitional development" for clubs, between age groups. This means that younger players use the same simple thought processes throughout their development, aging, and change of venues (with more players on the field the older they get).
What This is NOT
This is NOT an article about the best formations in soccer. This is not a reference for the Premier League, the MLS, or National teams. It is the basis for youth development that teaches players the right thoughts, decisions, and visual keys. It makes the transition between the age levels easier and more developmental. So, please don't argue about the best formation about winning. I don't do "winning soccer", I do teaching soccer. I really couldn't care less if we win our games. I want to know that we are learning, getting better, and developing with long-term goals in mind. This has not always been my attitude. Much like everything in life, it takes us a while to mature.
The Diamond Formation
We have to keep things really simple for ALL levels of youth players. We do not want to restrict creative activity and thoughts, but at the same time we want to teach the game and certain thoughts early on. To do this we start the diamond. We all know what the diamond shape looks like. It has four points, one at the top, one on each side, left and right, and one at the bottom.
So, assuming the ball is starting at the bottom point, nearest our goal, we want to get the ball to the HIGHEST point, which is the top, near the opponent's goal. If that pass is available and safe, that is the one we make (Option No. 1). If not, we pass it left or right to the open player (Option No. 2 and 3). Now that player should try and get it to the TOP of the diamond. If not they simply pass it back or across. This continues until we can get the ball to the highest point. The shape of this game naturally teaches what the coach wants to teach--three passing directions. Forward, sideways and back.
This is especially important near the midfield. You'll constantly hear coaches preaching to their players, "Keep the ball, play simple, find feet" and more. Often the team that can control the midfield is the one that has the most success. Having MANY options is critical to players in the midfield.
So now you should have the single diamond visual in your mind. This can also be used as a good warm-up game for all levels of players. Use a 20x20-yard square, four offensive players with one or two defenders. You can play a simple game of keep-away that helps players look for open lanes, good passes, and keeps them moving into open space for support.
