This achievement will take around ten hours to complete.STEP 1: Debut
Make your VOLTA Avatar and complete The Debut story mode. This will take roughly two hours to complete and you'll reach the rating of 83. Make sure to complete all the matches and training in this. It's super easy so don't worry.STEP 2: Featured Battles
Head into Featured Battles and complete all these on Professional difficulty if you can, it's fine if not it will just make the process a little bit quicker for you. Complete all the game until you've unlocked both the Liverpool Jersey and Mbappe for your own Volta Team.
You receive a Skill Point after each game, sometimes even three. Once you've completed both the Debut and Featured Battles continue playing the Featured Battles teams. Select First to Five Goals and put it on Beginner difficulty so you can complete a match in roughly one minute. STEP 3: The Skill Tree
75 Skill Points is the max you can have. I'll add a screenshot below to show you what I have equipped and I was able to reach the VOLTA Avatar rating of 92 in the ten-hour EA Play trial. Avoid equipping things like Skill Moves, Weak Foot, Finesse Shot, etc because that doesn't contribute to your overall rating.
