Arsenal against Nottingham Forest on the opening weekend of the Premier League was delayed for 30 minutes because of an e-ticketing issue.
There were reports that 35,000 fans remained outside Emirates Stadium at 12:30 BST, the scheduled kick-off time.
The game kicked off at 13:00 BST when more supporters had made their way inside the ground.
It was the first time Arsenal have used the new e-ticketing system for a Premier League game.
