Whoa whoa whoa, look at this from the BBC...
The government's national mourning guidance states cancelling or postponing sports fixtures is not obligatory and "at the discretion of individual organisations", including on the day of the state funeral.
On the day of the funeral, the guidance suggests events could be rescheduled so that they do not clash with the timings of the service and that organisers could hold a period of silence or play the National Anthem at events, with players wearing black armbands.
Now why couldn't the games have gone ahead with the national anthem and black armbands? That'd have taken care of stray shouts or chants.
The PL are spinelss gets.
