Is this result of careless programming or plainly intentional?

[Celtic]

My team:

just won the league and reached the cup final
players in top form,
full morale,
3,75M bonus,
home advantage
15% total supporters

The opponent:

is inactive (doesn't attend games or has supporters)
didn't promote
has his team all messed up (just a few reserves with contract)
goalkeepers playing mid-field
defenders playing strikers

In game:

I had 80% possession
overwhelming stats

BUT, commentaries were describing a dominant opponent with aggressive and successful play always threatening to score.

AND I was always chasing disadvantage, with his misplaced GK and Defenders threatening my goal and his attackers doing outstanding defence.

Do you believe that the bottom team of the Premier League would stand any chance against the Championship leader just playing with reserve players? even worse, players completely out of position, with no strategy and no manager?

What the f* is this game then?

Is all the game action and decision out of our hands?
What are the real factors that decide the outcome?

All identical except the winning bonus. Abandoned team, fulll of 2 star players, attacking goal keepers...

The question remains... Where is the f.... logic of this game? I honestly would love to see by myself the programming behind this.

Can any programmer from Nordeus tells us how are results calculated?
