Central Midfield Defending
A Tactical Look At The 4-3-3 Formation
With many permutations out there (semantics, mostly, distinguish the 4-1-4-1 from the 4-2-3-1 and the 4-1-2-3, etc.) the 4-3-3 is rapidly gaining favor at many levels of the game. Haverford runs a basic 4-3-3 with two holding central mids, and is the general inspiration for the discussion below; many pro teams use similar set-ups, as do a great many college programs. Not only are there many basic decisions to be made when two teams in a 4-3-3 (or 4-2-3-1, etc.) meet, but those decisions must be made at such high speed (with low occurrence of error) things can go from perfectly fine to total defensive breakdown in the blink of an eye.
For the LMSC readers, it is obvious that U12 players struggle with the team shape defensively. Some of this is due to a total lack of confidence in the ARs...who wants to hold a shapely line when the AR may well blow every offside call? Some of it is the comfort level of holding a line together; players feel safer if they have a bit of space in front and some time to see what's coming at them...though this comfort may quickly evaporate when it turns into a 2 v. 1!
College watchers will recall that most college back lines are too anxious to drop off as they are attacked, leaving easy spaces for the opponent to possess or switch play left and right in front. Additionally, such deep lines of defenders make the subsequent attack upon regaining possession that much more difficult as the move must be built from so deep a location, and under the added pressure of any turnover being far too close to goal to survive.
At the end of the day, having been around plenty of amateur soccer, the main concern prior to teaching group defending is ensuring that you can find 11 players who can defend individually. And given that every college team I've worked with does the same 1 v. 1 defending work (whether I'm in charge or not) as my U12s, we can safely say that youth soccer is not teaching effective defending at the individual level. It doesn't matter if they stand in the right shape/spots...if the opponent can run past, the rest is moot. Bottom line, putting the cart before the horse hasn't worked since they invented the wheel, and it won't work now. Players must master the 1v.1 aspect before there is any point in addressing the team facets.
