Arsenal's clash at home to PSV on Thursday has been postponed - leading to increased doubts over Chelsea vs Liverpool going ahead at the weekend.
Explaining the decision over the midweek Europa League clash, a UEFA statement said: "This is due to the severe limitations on police resources and organisational issues related to the ongoing events surrounding the national mourning for Her Majesty Queen Elizabeth II."
UEFA have confirmed a new date will be 'communicated in due course' with the fixture calendar already stretched given the upcoming break for the World Cup in Qatar.
