In Team Korea's first match at the Brazil World Cup against Russia, forward Lee Keun-ho connected on a long range goal.
The ball seemed to be in grasp of the Russian goalkeeper, but bounced off his hands and found its way into the net.
The Brazuca -- the official match ball of the 2014 World Cup -- has been pointed to as a possible reason behind the Russian player's miscue.
It has deeper and longer seams, which contribute to its aerodynamics.
Its unique surface makes it less air resistant.
Therefore, offensive players will find it easier to roll the ball with greater speed and accuracy, while making it harder for goalkeepers to snare.
"Simply put, it is like a volleyball. It will be hard to catch if the goalkeeper doesn't have a sensitive reaction to the ball."
To prepare for the Brazuca, Team Korea used a smaller ball during training.
"I was able to enhance my concentration by using a smaller ball during training sessions. As I have to dive for the ball faster, it requires more agility."
The Brazuca has made the Brazil World Cup a high scoring affair.
There's been an average of three goals per match so far, a figure not seen in more than 40 years at a World Cup tournament.
Faster and stronger -- the Brazuca may indeed be a deciding factor in future matches.
