If you play golf, cricket, baseball, pool - in fact any game that involves the use of some sort of implement for taking your shot, you pretty much know when you have made a good connection with the ball. When you make the perfect connection it is even better. In football there is no implement apart from your own foot and when you make that right connection with your foot and the pass or the corner is perfect - and what about a long range free kick? 

Below is such a free kick scored for Suwon Bluewings from South Korea by Australian Eddy Bosnar. I always enjoy a good strike and when they are just super powerful like this one they just make me go "wow"
