Thousands of West Ham supporters took to the streets before their Crystal Palace clash, demanding that chairman David Sullivan and vice-chair Karren Brady step down from their positions.
The massive demonstrations saw fans marching to the London Stadium with banners and flags calling for immediate change at the top.
Messages displayed by protesters included demands that the pair "just resign" and accusations they were "killing the club."
One particularly striking banner declared "sold us a dream, we are living the nightmare."

The protests come as Graham Potter's team sits in 18th place in the Premier League with just three points from four matches.
Two distinct marches converged on the stadium, with fan group Hammers United organizing the larger demonstration along Marshgate Lane leading to the directors' entrance. The protest wrapped up 45 minutes before kickoff.
A second march, arranged by Crossed Hammers, saw hundreds of supporters walking from Stratford train station through the Carpenters' Arms pub before reaching the same entrance point.
The fan groups aren't stopping there. They've planned a boycott for the October 20 home match against Brentford, aiming to leave visible empty seats during the televised Sky Sports broadcast.
This marks what organizers call "the start of a sustained campaign" of lawful protests.
Why are West Ham fans protesting?

The fan advisory board, representing over 25,000 supporters, had already issued a vote of no confidence in the club's board two weeks earlier.
They pointed to the club's inability to capitalise on their 2023 Conference League triumph - their first major trophy in 43 years.
Hammers United didn't mince words about the situation. They declared that "with Brady and Sullivan at the helm our club is going to die" and warned of "serious decline and dying a slow death."
The group insisted the pair must have "no more involvement" in running West Ham, calling for the club to be "handed over to professionals with the expertise and drive to move the club forward."
The club responded to the growing unrest by stating they were "continuing to listen to fan feedback" and had made "significant investment into the football operation."

"The most important people are the fans. That's what the football club's here for," he said, adding that everyone at the club was "hurting" from their poor start.
Potter, who's won just six of 22 league games since taking charge in January, emphasised the need to focus on improving performances.
