There are many ways to go about this achievement, this is how I did it. This has a very long and tedious setup but this got me the achievement in both versions after my first season on my first try. Please let me know if you get different results.

What you're going to want to do here is go through every single team that's ranked above 80 and move all their players rated 86 and above to the German club of your choice. Eventually you'll get a message "This team has to have (x amount) of (position players), so go to your German team and move some of your lowest rated players to the team you're pillaging so you can keep moving the good players.
Be sure to move #20 S. Kerr of Chelsea to your German club, she's your biggest competition in this achievement.

- For Origin Story select "Great Expectations"
- Select your loaded German club
- Advance through menus until you get to Game Settings. Put Difficulty to Beginner, UEFA Women Competitions to Off, all other settings don't matter
- Tab over to Stimulation Gameplay and adjust all the sliders in your favour while nerfing the CPU
- Advance and save your New Career
- Assign all your Skill Points, focusing on Pace, Shooting, Dribbling, and Physical first. These will raise your overall score faster than the other stats
- Assign your Playstyles. Pick whatever, it doesn't matter

From here you want to advance to your first game. From here, select Training and add any three drills that are ranked "Light". Play through these drills, doing your best to get an "A" grade on at least one of them. If you go lower than a "C" repeat the drill.
After this play the game and score three goals as quickly as you can. It should be no issue with the difficulty and sliders in your favour. Once you have three, pause the game and select "Request a Sub".
A note on all the notifications: I ignored every single one of them. People say to make sure you clear them all out, but I found it made no difference and a lot of them glitch out anyways.
Advance to your next game and select Training. This time press the Y Button to load your previous drills and select Simulate All. This is a very important step because doing Training keeps you in as a starter, which is vital for the achievement.
Play the game, get your three goals, and sub out. That's basically it. Repeat this for the entire season, keeping in mind your can completely sim past the International Friendly games because they have zero impact towards the achievement.
When the second season starts, you'll have to keep this process up as the Ballon d'Or isn't awarded until November. When I tried simulating to November 1st, or even the last week of October, I missed the achievement in both versions so I highly recommend playing games all the way to the first week in November.
Playing all the way up to the first week of November, I got a cutscene of the awards presentation where my player won and I got the achievement right after.
