Their are a number of attributes that are crucial in order to be a top drawer goalkeeper; being capable of moving off your line is one, while aerial dominance is another. However, arguably the most important tool in a keeper's locker is his reflexes.
The stoppers who have the fastest reflexes and, consequently, the best shot stopping skills, form the group of the finest goalies in the world - so which current keepers have he fastest reflexes in football?
Here are 7 of the best...
1. Manuel Neuer
Still probably the world's best keeper, Neuer's superiority almost won him a Ballon d'Or in 2014. But despite only coming third, the German national team skipper's ability has never been in doubt.
Despite exiting the Champions League at the quarter final stage with Bayern Munich this season, the 31-year-old showed off his incredible reflexes in an inspired performance against Real Madrid at the Allianz Arena.
2. Jan Oblak
Another man-mountain who has saved his best performances for the Champions League, Atletico Madrid stopper Jan Oblak has come on leaps and bounds after filling the void that Thibaut Courtois left a few years ago.
The Slovenian international is still only 24 years of age, but his superb reflexes and shot stopping ability has already put him amongst the world's elite, in what is only his second full season as Los Colchoneros' number one.
3. Kasper Schmeichel
Just like his father before him, Kasper Schmeichel is very difficult to beat one-on-one. Having now come out of dad Peter's shadow, mainly as a result of Leicester City's incredible title-winning season, Kasper has forged his own reputation as a quality goalkeeper.
Having spent years in the lower leagues, the Danish international returned to the top flight with the Foxes and has been instrumental in both their Premier League crown and their run in the Champions League.
4. Iker Casillas
Jose Mourinho almost destroyed the legendary Spanish keeper's reputation by dropping him from the Real Madrid starting lineup several years ago. And although Casillas did leave the Bernabeu eventually, he has redefined his legacy at Porto.
Casillas is undoubtedly one of the true greats and was the last line of defence in Madrid's Galacticos side. Despite not being the tallest keeper, the 35-year-old makes up for it with his lighting fast reactions.
5. Hugo Lloris
Similar to Casillas in stature and in style, the French national captain commands the Premier League's best defence and has proven season after season why he is one of the most revered keepers in Europe.
Lloris has been with Tottenham Hotspur since 2012 and could still win the Golden Gloves this season, which would be a testament to the 30-year-old's incredible displays in goal over the past few years.
6. Gianluigi Buffon
The king of the goalkeepers and quite possibly the best of all-time, Gianluigi Buffon has maintained performances at the highest level for over two decades at both club and international level.
Now in his 40th year, the Juventus and Italy keeper is on course for a famous treble with the Bianconeri if his side manage to win the Champions League this season, which is ironically the only trophy which has eluded the veteran stopper.
7. David De Gea
Manchester United's most consistent performer in what has been a disappointing transitional period for the Red Devils, De Gea has, at times, carried the entire team on his back with some outrageous individual displays.
It is no wonder that Real Madrid are continuously linked to the Spanish international, although his brilliant reflexes would surely warrant a world record breaking bid for a goalkeeper if he is to move.
