All decided at the beginning ?

Good Morning,
from a few months to Top Eleven game , I admit that the game involves me positively and I follow him enough but I have the impression that everything is already established at the beginning .
Let me explain, until the last days the results reflect roughly the strength of the teams , the modules deployed , the possession given by the fans but when you get to the last days known results strangest . Last jogging with early if they do not win even despite the presence of the manager and the fans while the opponent does not follow and has fans .
Results " recovered " to 90 minutes with a draw in extremis despite the quality is superior ................... !!!!!
and ' only ever impression ?

Excuse my English is not perfect
