There are plenty of high quality players in the Premiership, and they are capable of being hugely influential for their teams as they look to achieve their ambitions.
The big players need to step up when there is an important situation in the game, and taking penalties is one of the most important tasks assigned to a player. Though not much credit is given to the penalty takers, it is one of the most difficult roles considering that it is most likely to be one of the most pivotal moments in a game.
Also, the penalty taker needs to be extremely composed in front of goal, as missing a penalty is one of the worst feelings for a player. There will always be missed penalties, but it does take courage and belief from the player to step up and take the next penalty as well.
