To unlock the What a Shot! trophy in FIFA 19, you will need to score a goal with a defender from 25 yards or more.
The easiest way to do this is to adjust the gameplay sliders in settings as follows:
User Customisation:
- Shot Error = 0
- Shot Speed = 100
CPU Customisation:
- Goalkeeper Ability = 0
You can also change speed and acceleration settings so that your players are extremely fast and the CPU players are really slow.
Start the game, pass to a defender until you're about midway into the opponents half and shoot with full power. It might take a couple of tries as you might miss the target/keeper saves, but should be pretty simple to do.
