Spain and England met in Sydney’s Stadium Australia for Sunday’s final in front of a sold out crowd.
The showpiece event was briefly halted as the intruder ran onto the pitch in the 24 minute before they were tackled by stewards.
There was a small delay as England prepared to take a free-kick but the incident was dealt with quickly and play quickly got back underway.
The invader, wearing a mask, was seemingly protesting against Russian president Vladimir Putin.
They were wearing a T-shirt featuring a picture of Putin likened to former German dictator Adolf Hitler with the message: “Stop Putler.”
The back of the shirt showed a photo of the Ukraine flag accompanied by the slogan: “Free Ukraine.”
Spain took a 1-0 lead into-half time following Olga Carmona’s goal to put them into contention to win their first World Cup.
