Your video is a bit confusing. Let's say you make counter formation but than you need to know how that counter formation works. And you need to repeat this almost every game. Is that formation more suitable for attacking or defensive? Better for possession or counters? How to defend with it? And so on. Let's say you end up with 4-5-1 flat but it would be pointless to play attacking with it. And if you dont know this formation how you can know that attacking football wouldnt be suitable for it? Or those fansy formations? It's like i construct them but i dont know how to use them.
You say that you should use 2dc against 2st and so on. But what if your defenders are weaker than oppo attackers?
