It's no secret that Brazilian fans live and breathe football, and their supporters are renowned for their passion which can, in certain circumstances, turn downright ugly and dangerous.
On Sunday, a goalkeeper was on the receiving end of some dangerous antics conducted by Gremio fans as they launched rockets towards his goal in a bid to distract the shot-stopper.
As their team attacked inside the opposition's half, footage appears to show the Gremio supporters launching a rocket at the goalkeeper.
Yes, it was foolish and dangerous but the original method seems to have reaped rewards after the distraction technique resulted in a Gremio goal.
Moral fans rest assured, the goal was disallowed by the match official. Indeed, its not uncommon for fans to hurl abuse and even objects at opposition players in a bid to destabilise their team's opponents but these Gremio fans have taken "being the 12th man" and fighting spirit to a whole new, and nasty level.
If these sort of diversion tactics employed by the club's fans are a regular occurrence, its no wonder Gremio currently sit comfortably top of the Gaucho 1 division. And if this kind of behaviour goes un-punished by the Brazilian FA, its likely they will remain at the top for a while longer...
Not the first time
It might not come as a huge surprise to know that the Gremio faithful are no strangers to off-field controversy, as the Daily Mail recently reported.
The Brazilian outfit were banned from this year's Brazilian Cup after fans racially insulted an opposition player in a match dating back to September 2014, as well as being fined £12,500 after the case was bought to a tribunal.
