WEST HAM fans stormed out of the stadium after Chelsea ran riot at the London Stadium.
The Hammers opened the scoring in the sixth minute but that was the last thing the home faithful had to cheer.

Chelsea took just nine minutes to level, through Joao Pedro, and it was one way traffic from then on, although West Ham did have a goal chalked off for offside after a VAR check.
Pedro Neto scored after that to give the visitors the lead before goals from Enzo Fernandez and Moises Caicedo sunk the Hammers.
Fernandez’s strike led some fans to take an early half-time, with the fourth goal sparking a mass exodus.
Supporters began leaving the stadium in their droves before the hour mark.
THIS IS A DEVELOPING STORY..
