Arsenal say they are "very disappointed" after police moved their Premier League fixture against Chelsea at the Emirates from April 29 to May 2.
The Gunners are fighting it out with reigning champions Manchester City for the title and currently boast a six-point cushion, although Pep Guardiola's side have a game in hand.
The teams also meet at the Etihad Stadium on April 26 - a match that Arsenal were set to follow with an all-London clash against Chelsea on April 29.
But the Premier League has announced that the fixture is being switched from its Saturday night kick-off to the evening of Tuesday May 2 due to the local police's request.
A Premier League statement read: "The initial scheduling of this match was approved at a Safety Advisory Group (SAG) meeting in February.
"However, the Metropolitan Police has now revised its position regarding the kick-off time and requested a further SAG meeting which determined the match had to be rescheduled.
"We regret the need to move this fixture at late notice and the impact this will have on supporters.
