Factual error: In the final football game scenes ( from about three-quarters of the way through the film or so) all the spectators are wearing 1970's clothes and have 1970's hairstyles.

Plot hole: In the scene where Colby is discussing tactics with the team, Pele interrupts and takes the chalk from Colby and says "Hatch gives me the ball here, I do this, this, this, this, goal" while drawing a line on the blackboard to indicate dribbling from one end of the pitch to the other. At that point in the film, Hatch was only the trainer, not the goalkeeper.
