You can use any striker with the Distance Shooter trait really but to make this easier:
Go to Kick-Off
Choose the Classic XI squad as your team.
Choose Macclesfield as your opponents (worst team in the English league, if not the whole game).
Change the difficulty to Amateur.
Make sure you have both Shearer and Butagueno up front (these guys are stupidly powerful and accurate.)
Just pass the ball to these guys and make sure you shoot from outside of the 18-yard box. Hold RB and use a finesse shot too if you prefer. Keep at it, it will come quickly.
