Are you ever wonder why you couldn't complete this objective forever, just watch this video and repeat the step then you're all done. First you need to have one player running toward the goal, then press L2/LT + Left analog push behind, pass to player behind you and just hope the ball go in. When you done properly the commentary will say it was a back heel pass, if they didn't mention mean you did not do it properly and need to try again! Hope that help!
