I don't get to see what you complain about really. You have a great player which you train and care about, and he scores tons of goal for you. Then why do you care about other people's player as well?
Football is a team sport, the game engine takes a lot of factors in the simulation. The fact that the two players have the same goals doesn't prove anything.
Do you see a 32% difference? I spent more game resources, time and money on my player, and the result is the same.
If the game "decided" that you will lose, you will lose.
