Your Formation
I thought I might try and explain a little why that formation will have difficulty succeeding.
In the modern game control of central midfield is paramount. Whether you choose to shut down your opponents chances to pass/dribble through the middle, or control the middle through passing and possession, you have to have a significant presence in the middle to make sure your opponents don't dominate the game.
most teams will actually use 3 or more center mid-fielders to accomplish this, especially in leagues outside of the UK. Fielding only one center mid is suicide both defensively and offensively. he will be passed/dribbled around, as well as ganged up on when he does manage to get the ball himself.
Remember the 3v1 drills as a child on your school teams? Imagine if you had to deal with that all game.
