FIFA 22

Can be done in a solo game against bots on any difficulty level. At the Volta screen, press Y on the leftmost option, and select Volta Battles. Keep playing these battles (you can choose Beginner or Amateur if having issues) to get XP. Once you get enough XP to level up to Level 7, the achievement will pop.

PS: I started the game already at Level 6. Not sure if it's the same for others.

This is the "easy" guide for mutiple achievements in VOLTA FOOTBALL:
Volta's best
On the way up
Full wardrobe

"Full wardobe" will be the last achievement you probably need, because to buy 50 items you need to reach arround Level 12.
Level 12 needs 4750 XP.

Here is the trick:
Play Volta Battles -> Select an opponent -> choose difficulty professional to legandary -> play as team -> score 5 own goals in about 20-30 seconds (to skip celebration cutscenes press RB+LB) -> gain 45XP for a loss -> repeat

By far the quickest method to gain XP, rank up to level 7 (for the achievement) and beyond to buy items in the Volta-Shop + get Skillpoints every game to get past a player rating of 90.

Keep in mind you can get the Xbox One Version + the Series X Version Achievements just by boosting yourself on one console. I did the Xbox One Version first, started the Series X version afterwards and all 3 achievements popped.
