Crowd invasions are a part of the whole European football experience- the HQ gets that.
But the Tottenham-Partizan Belgrade match got completely out of hand with interruptions that, it turns out, were part of a Youtube prank.
Here's one of the invaders doing his thing
The game had 41-minutes of delays because of people running onto the pitch.
Players had to leave the pitch, go back into the tunnel, and come back out onto the pitch to complete the 1-0 Spurs win.
