Hello folks!

I wanted to do this guide, because I saw a lot a people had problem with this achi' as I had too.
So, the details, I've got it with this settings:
Sweden(Player) - Nigeria (CPU)
Normal speed
5 mins match
No wind
Easy level

>> Why Sweden?
+ Because every goalkeeper "knows" the scorpion kick, but the goalies with 4 or 5 stars rating can get the ball easily by hand.
+ Better to try with less than 3 stars. Best option is a 2 stars goalie.

>> Why Nigeria?
+ Because they cannot do "precise" shots, mostly do "lobbed" shots.

>> Are "lobbed" shots good?
+ Yes. Best chance to perform a scorpion kick.

>> How to increase the chance of a scorpion kick?
+ Take the ball and do a "lobbed" pass to your goalkeeper. (yes, you probably will do a lot of own goals :D )

Best place to do that, just outside of the box. (on the middle)

>> How to do a "lobbed" pass?
+ Not just press the 'pass' button, hold it for a while, but not too long, because it will be too strong. :)
+ You have to try and feel the best way.

Set at least 5 mins for matchtime, because you need time to trying. :)

With this technique i've got the achi' for the first try!

I hope I could help! Good Luck! :)
