The basic process for taking a shot doesn't change, but if you want to make your shots potentially unstoppable with this accuracy and power boost, it's as simple as tapping the "shoot" button a second time after the initial button tap.
But that's the easy part; what makes this mechanic a challenge is timing your second tap perfectly; if you tap it too early or too late, it could actually make your shot a little bit worse. With the FIFA Trainer turned on, you'll see a colored bar over your player's head with sliders. Your second tap should be right when the sliders hit the green zone in the middle. If you successfully unlock a Timed Finish, you'll see a short message above the bar that says, "Great Timing!"
Becoming a Timed Finishing Master
Once you get the hang of the process, you can turn the Trainer off. While the bar and message will no longer appear during a Timed Finish attempt, you can still see whether or not your attempt was successful via the player indicator triangle. The triangle's outline will glow green if you have successfully achieved a Timed Finish.
Timed Finishing applies to any type of open-play strike, whether it's a header, volley, finesse shot, even a bicycle kick. But the more difficult and quick the shot attempt is, the higher your margin for error will be. Practice your timing with all types of shots so that you can master this and take your FIFA game to the next level.
