If there is one part of the game of football that is a paradox, it is the penalty kick. It is a shot that is both a formality and yet the most exciting moment in a match.

In the past couple of weeks we have seen two penalty kicks that have raised eyebrows for their keen sense of the rules as well as the controversy that they have stirred.

We have to start out with the one from the opening week of the J-League where Hisato Sato fooled the entire stadium

The art of kicking a penalty might have been revolutionized, but there have been moments throughout the history of the game where the formality of the penalty has been polished up a bit in an effort to give an edge to the kicker as well as keep the goalkeeper guessing until the last possible minute.

Let's not forget who started this, none other than Johan Cruyff at Ajax with his play back in 1981.

This would be imitated well over a generation later by Robert Pires but with not quite the same result.

One expert in the art of deceiving the goalkeeper was River Plate's Ariel Ortega. He was able to bring stutter steps, jitterbugs, and bunny hops into fray. That would later be perfected by Neymar against São Paulo.

What about this incredible sequence?

Roma's Francesco Totti has given us the best penalty kick never to have counted...

...and one of the worst to have ever been taken.

Totti does have bragging rights in Italy, because he was not able to do what Alessandro Del Piero did...

I guess we can all agree on one thing, none of these PKs will ever reach THIS level...

What was the worst or best penalty kick you have ever seen?
