Watch this extraordinary footage from inside the Manchester United team bus as it was attacked outside the Boleyn Ground on Tuesday night.
United's coach was late arriving for the Premier League clash - the final game to be played at Upton Park - prompting the kick-off to be delayed by 45 minutes.
The delay was caused by violence on the streets near the stadium with fans hurling cans and bottles at the away team's bus, causing windows to be smashed.
And this video, posted online by forward Jesse Lingard, shows the reactions of the United squad as the incident took place.
Many of the United players are pictured lying on the floor in the middle of the bus, but Lingard doesn't appear too concerned as he films himself and jokes to the camera.
Take a look at the footage for yourself by watching the video at the top of the page.
