A video uploaded to social media appears to show hooligans squaring up for an organised brawl.

It is claimed the fight is between youth firms connected to the two London-based Championship rivals from Millwall and Brentford far from any stadium.

The three-minute video shows the men - half of them topless - meeting on a muddy field surrounded by graffiti-strewn walls.

The event is said to have occurred on August 25th, however it was only uploaded to Facebook and YouTube on Monday.

It's unclear where the fight took place, but a spokesperson for the Metropolitan Police told Mirror Online they are looking into the footage.

As hooligans from either side face off, one man - dressed in a red jacket - appears to officiate, stepping in on occasions and separating combatants.

“Leave him, leave him, he’s had enough,” he says to one brawler, as he kicked a defenceless opponent on the ground.

At the end of the brawl the men shook hands and went their separate ways.

The video is described online as the UK’s first organised fight between rival fan factions - suggesting more to follow.

It mirrors footage of Russian hooligans meeting up for arranged fights in woods.

One user said: "Very poor fight and comical at times but in all fairness this is the first of its kind in the UK."

Another added: "It's embarrassing compared to the Russians hopefully more to come though and nice to see them show respect at the end."

Millwall return to Championship action on Saturday, when they take on promotion-chasing Leeds United at The Den.

Their fixture against the Bees isn't scheduled until November 3.
