To get this achievement, this is what I did.
Either go up the left or right side of the play field (do this in the first half, I found it much easier to go up the field) and be just outside of the goalie box. I tapped the
button to activate a centering lob to a teammate. If a player is nearby and in the correct position, hit the
button to shoot. The player should do an airborne kick into the goal.
A few hints that may help as well:
1. Aim your shot. There is no automatic shot scoring here. I can't believe how many times I've tried this technique and ended up just wide of the net.
2. Be patient. You won't get it the first try and thank god you only have to do it once. It took me a few games. You have to win 50 and score 100 goals anyway.
Hopefully this helps anybody getting this achievement.
