Before the half against Arsenal, thousands of West Ham supporters staged an unprecedented walkout.

Thousands of West Ham fans left the London Stadium before half-time as their team were torn apart by Arsenal in Sunday’s Premier League clash.

David Moyes’ side were 4-0 down at the break as goals from William Saliba, Bukayo Saka, Gabriel and Leandro Trossard gave the dominant visitors an emphatic lead.

Many West Ham supporters decided they had seen enough when Trossard’s goal two minutes into first half stoppage time – the fourth in 15 minutes – put Arsenal four up.

They headed for the exits of the London Stadium, with TV footage from above showing them streaming on to the concourses around the Stratford venue and heading home.

It sent an emphatic message to the West Ham players and manager Moyes, with talks over a new contract yet to result in an agreement.

His current deal is due to expire at the end of the season and supporters are split on whether he should get an extension.

For now, barring an unlikely second-half comeback, the inquest begins into a lamentable first-half performance against title-challenging Arsenal.

Sky Sports pundit Roy Keane branded West Ham an “absolute disgrace” for their meek display in front of their own supporters.

“They are not being physical, not tackling, nobody has laid a glove on [Martin] Odegaard,” Keane said at the half-time break. “There are ways to lose a game of football but the way West Ham are doing it…they look old, sluggish in midfield, no desire, no hunger.

“David Moyes must be fuming. All credit to Arsenal, they have turned up, flexed their muscles, they look sharp and at it. West Ham? An absolute disgrace.”
