Watch: No prizes for guessing what Manchester United fans sang when this steward slipped

Taking to the pitch to orchestrate his fellow Manchester United supporters' singing, this fan would have known it was a matter of time before a steward ended his fun.

Sure enough, it takes only a matter of seconds before the first official arrives on the scene...and falls flat on his arse - much to the amusement of the traveling contingent... https://twitter.com/NOT_MOTD/status/636783626907222016?ref_src=twsrc%5Etfw Predictably, the United supporters were quick to draw parallels between this and another slip... https://twitter.com/MikeKeegan_DM/status/636618922788278272?ref_src=twsrc%5Etfw Luckily for the steward, the pitch invader doesn't appear to have any plans of instigating a chase and is happy enough to be escorted away by the slipping official and his colleague.
