Revealing mistake: In the game against Liverpool, there is a reversed shot after Harris scores the first goal. It is fairly obvious since all of the players' numbers are backwards, in addition to the advertisements in the background.
Continuity mistake: During the final game against Liverpool they show Munez running to celebrate with Harris after Harris' first goal and Munez is wearing jersey number 8, but when Munez scores the final goal of the game he is wearing jersey number 26.
Continuity mistake: When Munez's boss is teaching him that the ball can travel faster than he can run, he has two balls which he kicks one at a time. As he kicks the second ball, he suddenly holds another one.
Continuity mistake: One night, before the game against Liverpool, Munez is kicking a line of balls into the goal. As he kicks the last ball, the shot changes to a view from behind the goal, and for an instant a line of 4 other balls are visible. In the next shot, they're gone.
Continuity mistake: In the last match against Liverpool, just before Milan Baros makes his own goal he kicks the ball outside the large area, but suddenly in the next shot he is inside the area, 12 feet away from the goalkeeper.
Continuity mistake: When Hernan is watching Santiago on TV at the bar in Los Angeles, the guy who tells him "if your son makes a goal, I invite you a beer" leaves him and grabs his beer, but in the next shot the beer is back on the bar.
The free-kick goal scored by Santiago (actor) against Liverpool in the movie was actually scored by the real Newcastle United player Laurent Robert in the real game against Liverpool which won them the game 1-0.
