The penalty kick has long been revered as a means of making or breaking a match. It can all come down to an individual player one-on-one with the keeper, and it makes for some of the best moments in football.
Some situations see it put a team ahead, draw level, finish an opponent off or win or lose a major championship.
At other times it can just be a moment that purely frustrates. Liverpool's Luis Suarez felt that burn when he missed an opening day penalty at home in August of 2011 that would have seen the Reds go up 1-0 and see him score the first goal of the new Barclay's Premier League season.
A penalty kick situation also allows for some of the most scrutiny a player can and will ever feel during his career. The spot can be the most lonely place on the pitch when the end result goes south, and all of the players that follow have felt that sting in various amounts of intensity.
