<p>Until now, the save percentage has mainly been considered as an indicator for evaluating a goalkeeper's ability to defend. However, this measurement does not consider the degree of difficulty of the shots taken, thereby limiting its usefulness. Hirashima (2014) performed a logistic regression on 551 shots on target during the FIFA World cup 2010 to clarify the causes of difficulty for shot stopping and to create a regression equation to quantify the difficulty of each shoot stop. It will be possible to objectively evaluate goal keeper performance using this equation. The aim of this research is to evaluate the performance of the goalkeepers who played in the FIFA World cup 2014 using this equation. The subjects was 32 goalkeepers who capped more than two matches in the 2014 FIFA World Cup. The data was gathered through match analysis. In conclusion, the goalkeeper who contributed most to decrease conceded goals in the 2014 World Cup was Keylor Navas (Costa Rica). He was able to decrease his teams conceded goals by more than 5 through shot stopping. His stop rate is a third compared to the average of other top-level goal keepers. There was also a positive correlation between the traditional evaluation method (Save Percentage) and the new evaluation method (Stop Rate). Although Guillermo Ochoa and Claudio Brave where positioned below 8th with the traditional method they ranked 2nd and 3rd with Stop Rate evaluation. Therefore, it is plausible to conclude Save Percentage does not provide legitimate evaluation.</p>
