Tottenham Hotspur and the Premier League have apologised to fans for the ongoing hold-up in confirming the club's home derby against West Ham United on New Year's Eve.
The match at Wembley, scheduled to kick off at 2:15 p.m. GMT, is due to be shown live on television.
However, Spurs are awaiting a safety certificate from a safety advisory group made up of representatives of the club, Brent Council and the police, ambulance and fire services.
A source has told ESPN FC that the delay is being caused by concerns over transport.
Transport for London fears that up to 85,000 fans travelling to Wembley for the game will put too much additional strain on staff and police, due to man a free all-night service on London's Underground and trains that night.
