A shocking video of a Millwall fan flooring a Spurs supporter with a single punch has emerged, as the two London teams met in the FA Cup quarter final.
In the footage, two men, thought to be Tottenham Hotspur fans, can be seen arm in arm, singing a tune in the direction of Millwall fans as they walk past.
After a while, two men wearing flat caps emerge from the crowd of supporters, when suddenly one of the men smashes the younger of the Spurs fans in the jaw, sending him crashing to the floor.
It came as armies of angry supporters were seen fighting with riot officers and hurling beer at one another as they lined the north London streets in their hundreds near Spurs' White Hart Lane stadium.
A match eagerly anticipated by both sets of fans, it seemed that a minority was more focused on wreaking havoc off the pitch rather than watching their team progress into the semi-final of English football's oldest competition.

Pictured: An angry supporter appears to make a lunge for a police officer on horseback outside White Hart Lane stadium
Dramatic photos show the police grappling with supporters and drawing their truncheons as they try to control the baying crowds, with one man tackled to the ground and another appearing to lunge for a policeman on horseback.
Groups from both teams were also reportedly heard singing racist chants after the trouble kicked off at around 2pm today.
According to the pictures taken outside the ground, a number of arrests were seemingly made as a result of the clashes.
But it appears that the majority were between police and fans, after the unruly gangs tried charge their way through walls of officers separating them.
The scenes will surely be concerning for the Metropolitan Police, with the last ever north London derby at the current White Hart Lane, between Spurs and Arsenal, just weeks away on April 30.
The match is a late kick-off with supporters potentially spending hours drinking in pubs and bars prior, as they make the most of the bank holiday weekend.
