Well, one question: Is this about the CCCs or about goals?
I have to say that shooting from distance can be considered a CCC but hardly works, while our opponents will have their CCCs inside the box. Besides patch errors, this is one of the things that has wooreid me about this tactics (excellent work, no doubt, just trying to help here, ok?).
I also noticed that overload will make players having too much pressure and will fail more, so why not attack, or even control? Overload means to attack not having many concerns in the back because you are desperate. If you are already losing 1-0, 2 or more will not make a difference, so all in attack is the way!
But not when you are trying to keep the other team at bay and try to get some 1 x 1s with the keeper! The SS is so anxious to score that he will shoot asap! And we don't want that! We just want him to run with the ball and get a very good chance to score.
i have tried counter, but with a such defensively formation, you will just be crushed.
About corners, use your strongest header to jump with the keeper and you will score. Not many but a few. I pay with Bayern and Martinez scored 4 in 15 games. I use the latest Bermuda's setup.
just my 2 cents
