The UK government's 'Plan B' measures were in full effect on Wednesday night as the Premier League looked to minimise the threat of coronavirus spreading.
Fans attending matches must complete a declaration to confirm they have had double vaccination or a negative Covid test before they arrive at stadiums, under Plan B arrangements.
The top flight has issued detailed guidance for fans, who will also have to show their NHS Covid Pass or proof of a negative test when they arrive at stadiums from tonight.
And that was evident on Wednesday night ahead of Arsenal's clash with London rivals West Ham.
