Start off by selecting kick off and select a side. You can play against beginner difficulty or plug in a second controller.
Select either Portugal or Al-Nassr (in the Saudi league).
The goal is to get it to Cristiano Ronaldo because he has the play style plus. Once you have passed it to him get within shooting range and Hold LB + RB at the same time and click B to do a power shot. Make sure you have good aim as this shot uses manual aiming so try and get close or sweaty the ball if you're having trouble.
Good Luck!
