Tottenham Hotspur face having up to 20,000 empty seats at their Premier League home debut at Wembley.
Nearly 70,000 tickets have been sold for Sunday’s clash with Chelsea to Spurs supporters already registered with the club before July 1, the Times reports.
Wembley can hold 90,000 fans for a football match but Spurs have been forbidden for putting tickets on general sale because the derby game is deemed high-risk.
The rule, which came after talks with Brent council, the Met Police, the London Ambulance Service and the London Fire Brigade, will also apply for the Arsenal game at Wembley in February.
Tottenham sold out all of their Champions League matches at Wembley last season.
There will be a bigger attendance at the Burnley game the week after because Tottenham are allowed to put tickets on general sale.
