Understanding role of Luck in top eleven

[Tactician]

Yeah, I see what you mean. The game engine isn't able to reflect that formation, it's probably something they should work on. It's probably someone figuring out some of the complexities of the game-mechanics to "exploit" the system, and not due to luck at all.

Is this acceptable to you? Or let me put it in a more appropriate way, it this acceptable to you if you were the victim and your team got knock-out of C-L or Cup or failed to win the final because of such anomalies?

There is definitely something 'fishy' going on. It could be intentional or it could be a malfunction or flaw. It could be due to the 'roll of dice' like Nik said, or it could be due to something else in this game or a combination of several things. For sure though, there is no football logic in the outcome of many cases that are similar to the above.
