Security staff were seen “rugby tackling people to the ground” after ticketless fans broke into Wembley stadium.
Around 300 fans breached security cordons, charging into the perimeter area of stadium before kick-off.
Many supporters had been celebrating on Wembley Way all day, clambering onto buses and setting off flares .
After the breach, entry to the stadium was briefly haunted as stewards and staff tried to regain order.
Wembley earlier insisted there had been "no security breaches of people without tickets getting inside the stadium", but during the first half confirmed "a small group" had succeeded.
A Wembley Stadium spokesperson said: "There was a breach of security and a small group of people got into the stadium.
"We are now working closely with stadium stewards and security to remove these people. Anyone inside the stadium without a ticket will be instantly ejected."
Some of the people inside Wembley said there had been fans standing on the concourse for the entire first half, watching the match.
âPeople who left their seat at half time were asked to show a ticket before returning, one said.
The 90,000-seat Wembley has a pandemic-restricted capacity of about 67,000.
