Ah, yes, the old "fall over and hit the ball with your head and then your teammate kicks it into the net" trick. Works every time. Or, at least, it works every time we have seen it tried, which to be totally honest is just this one time.
The other team will surely never be caught off guard during a set piece again, having fallen victim to this embarrasment. On the real, though, that strike after the silly play-dead thing was actually a nice shot, so these guys should get credit for that in addition to admirable creativity.
