Momentum is fixed in the game

They claim it is momentum but it happens so consistently that you dominate a player and then all of a sudden your team starts to lose so called " momentum " even though you had all the momentum,  suddenly it swings to other team in the second half not randomly in between the 75'-90' time and then you lose after being up by 4 goals or even more sometimes.  They should like in real life how often being down by more than 2 goals does a team all of a sudden comeback.  It happens so rarely that when it does happen it is historical.
