Arsenal will take on PSV Eindhoven in a rescheduled Europa League fixture on October 20 - meaning the Gunners' clash with champions Manchester City will be postponed.
UEFA confirmed earlier this week that this Thursday's planned fixture between Arsenal and PSV was called off due to logistical issues relating to the Queen's funeral.
The governing body said that there were "severe limitations on police resources and organisational issues related to the ongoing events surrounding the national mourning for Her Majesty Queen Elizabeth II".
