Just had a friendly with a weird result. I won 1 0 but the player who scored the goal had a rating of 0.0.

i assume players get rated mainly based on their primary duty. In this case, he is a defender who only made 3 tackles out of 19 attempts, including ten fouls. Despite the scoring, he had a pretty shitty display.
Then again, a 0 rating is absurd.
