With the full backs on Automatic they will naturally venture forward and take part in attacking phases of play. Your target man will look to lay the ball onto the nearest player iif he cannot create a shooting opportunity. With the wingers, assisted by full backs, and Nolan going forward you instantly have 5 breaking from deep. A box to box is exactly that, he will go from defense to attack along with the play, that makes 6. Tempo is how fast your players pick out a pass, at that level you're asking your players to effectively play one touch football, something I very much doubt they have to attributes to pull off. Decisions and passing would need to be above 15 for your midfield to stand a chance in those settings. The effect you're aiming for is simple to implement, play a more direct game and increase the wingers and AMC's mentality slider a little, just to give them a more attacking approach.
Another thing I have found useful in my testing of the 4-4-1-1 is moving the wingers forward in games you are dominating, this effectively gives you a 4-2-3-1, a much more attacking option, in the tighter games though 4-4-1-1 should be quite solid.
