Napoli fans celebrate goal with human avalanche onto the pitch

When Marek Hamsik scored in the 18th minute to give Napoli a lead and an away goal against Villarreal in their Europa League match on Thursday, he celebrated in front of his side's traveling fans. And the first few rows of those traveling fans took an unexpected trip to join him on the pitch when a barrier broke, sending them tumbling to the ground like a waterfall of bodes.

Scenes like this conjure flashbacks to tragedies past, but thankfully only a few people suffered relatively minor injuries in the group tumble and most climbed back up to watch Villarreal score two goals just before halftime to win 2-1. Since the first leg ended 0-0, Villarreal advance, dumping Napoli from the Europa League like their fans from that stand. So, in a way, this incident was really just a bit of foreshadowing.
