Arsenal and Chelsea fans stood together at Wembley to pay tribute to the victims of the Grenfell Tower tragedy.
At least 80 people died in June when a fire broke out in the tower in Kensington.
And before the football season's traditional curtain-raiser at the national stadium, the Choir for Grenfell sang "Bridge Over Troubled Waters".
Both sets of supporters displayed flags that read "For Grenfell" before wreaths were laid prior to kick-off.
The 90,000 fans then fell silent as those who lost their lives were remembered.
The two clubs, who met in last season's FA Cup final, will donate their match fee to the support fund, with the FA expecting as much as £1.25million to be donated.
Members of the victims' families and survivors were also in attendance, along with members of the emergency services.
Donations of £3 can also be sent by texting GRENFELL to 70007.
Today's tributes follow Arsenal's own last weekend when they invited 400 service men and women to the Emirates Cup.
Gunners boss Arsene Wenger said at the time: "Many of the firefighters were directly involved in the response to the Grenfell Tower Tragedy.
"Heroic is a word we will often hear in a football context but these brave men and women truly embody what it means to be a hero.
"I know the club’s community department also worked hard to help with the relief efforts at Grenfell.
"Everyone here at Arsenal was shocked and deeply saddened by events in west London and we send our deepest sympathies to those many families affected."
Arsenal right-back Hector Bellerin raised £18,000 for the fund earlier this summer.
The 22-year-old announced before the European Under 21 Championship that he would donate £50 for every minute he played for Spain in Poland.
He eventually made four appearances, in which he played the full 90 minutes in each, before his side lost 1-0 to Germany in the final.
