Formation counter is not about the final score, its about how many chance the team created, the chance creation ratio.
Chance created is the number of shots plus the number of enemy tackles. So, I have achieved a chance creation ratio of 52:34 in this game, making the game highly in my favor.
It was a CL game 2 days ago, my default formation is one of the hardest counter against any formation with 1~2 ST and single wingbacks as flanks (such as 41212 or 43N12). It is also effective against may popular formations including 451v and 442 but not really as hard, so I call it a soft counter.
Even if you have created more chances you can still lose because the form of your players is a huge factor.
