Okay so first off just start a kick-off match as a team you know has a good striker. I chose Arsenal.
Secondly, choose a bad team preferably with horrible defending to play against. I chose some random Korean team.
Next you need to change the difficulty to amateur and extend the match time to 20 minutes to ensure you have long enough.
Once you start the game go to the pause menu and then settings and change all the CPU and player sliders to suit yourself. This will ensure the actual game is an absolute breeze.
Now its time to actually start playing. First off I suggest crossing it in from the wing and trying for the header first. The first one to score with a header should be the one you use to get the left footer and right footer. This ended up being Ozil for me.
Because the opposition is so blatantly horrible at anything just keep passing to the player who scored the header and keep shooting from just outside the box and you'll eventually score with both feet and voila! Done and dusted!
Hope I helped!
