When Jess is playing in her first game for the Harriers, after/while she scores she is shown wearing her new silver and red Adidas boots even though she hasn't bought them yet.
When Jules is shown in the game (when she and Jess aren't getting along) after Jess scores, her jersey is inside out.
In the match where Jess and Jules aren't getting along, Jules' hair is held back by a metal headband, except in one close-up where it is held back by a thick, black headband. It then goes back to the metal headband. Then in the final game Jules is wearing the black headband again.
During the final match (while Jess is still changing in the car), when the first goal is scored, a completely different ball is shown going into the net.
When Jules is in her bed depressed, she takes the picture of her and Joe and crumples it. But when it is seen in the trash, it only has a few creases in it and it looks pretty intact.
Both the Paxton and Bhamra families accompany their daughters all the way to the departure gate when they're leaving for America. Since the 9/11 terrorist attacks, non-ticketed individuals are not allowed past security.
The speaker during the match which is supposed to be in Hamburg speaks German with an English accent and makes typical English errors (e.g. he says "... Elfmeter ausgeführt bei Nummer 7 Jess ..." instead of "... durch Nummer 7 ..." announcing the penalty)
At around one hour and 35 minutes, when Jules and her mother are arguing in the car their mouths aren't moving.
A crew member was in the back seat, rocking the car at the airport that Jess's sister and her fiance are in alone. At one point three heads pop up over the seat.
When Jess takes the free kick at the end of the match the goalkeeper positions the wall then stands on the wrong side of the goal behind the wall making it easier for Jess to score.
Jess's team, Hounslow Harriers, is playing Queens Park Rangers (QPR) in the final. A woman wearing a QPR scarf is sitting behind the Harriers' bench and is seen cheering after Jules and Jess score goals against QPR.
