The ultras of AC Milan and Venezia had a battle at sea on Sunday and footage of the scenes makes for incredible viewing.
The Rossoneri travelled to Venice for the away fixture at Stadio Pierluigi Penzo and some of the club's most passionate supporters decided to travel on boat.
But Venezia fans were also on a vessel on the waterway and some utter madness ensued.
There was smoke bombs and flares set off all over the place, with both basically having a naval firework war with one another ahead of the game.
Clips of the borderline combat were posted online and quickly went viral.
Ultras going head to head is nothing new in football, but it's not often you see such events happening in the 'City of Water'.
Milan won 3-0 against 10-man Venezia, with Zlatan Ibrahimovic bagging two minutes in and left-back Theo Hernandez helping himself to a brace.
Venezia were promoted back to Serie A last season after a 19-year spell away.
Having spent time lurched in the Serie B, Serie C and Serie D, they finally sealed a return to the top flight after beating A.S. Cittadella in the play-off final last year.
They bounced back with arguably the kit of the season and currently find themselves 17th in Serie A, four points clear of the relegation zone.
Their squad includes former Manchester United goalkeeper Sergio Romero, as well as Chelsea loanee Ethan Ampadu.
