It is four years to the day since Divock Origi sparked mayhem at Anfield with a 96th minute winner against Everton in the Merseyside derby.
In classic Origi fashion, the striker had only entered the pitch 12 minutes prior to the goal as Jurgen Klopp played his trump card with the score locked at 0-0.
Jordan Pickford's mistake in front of the Kop allowed Origi to head in from a yard out - much to his own surprise. What followed was complete chaos - a pitch invasion from Klopp and a subsequent apology, as the momentum from that win pushed the Reds to a Champions League triumph.

The match itself will never be forgotten for Liverpool fans, as it may well have been the catalyst for the team to go on and achieve unbelievable success under Klopp.
Liverpool's win over Everton was yet another Merseyside derby win for the Reds, but it was also a win that took them to within two points of Premier League leaders Manchester City.
The Reds were in the title race for the first time under Klopp and the Anfield faithful were there for the ride.
Elation took over Klopp's body once Origi's header hit the back of the net and the German sprinted on to the pitch and straight into the arms of Alisson Becker on the half way line. As he said in the post-match interview he 'couldn't stop' himself.
What followed was an apology to Everton boss Marco Silva: "I have to apologise because I didn't want to be disrespectful but I couldn't stop myself," Klopp told Sky Sports. "It just happened!
"The plan was not to run [onto the pitch to celebrate]! When I chose to stop I was close to Alisson. He was surprised! It was the last situation of the game. Both teams delivered an unbelievable fight.
"If I could describe it [how he feels] then I would have control over it. We don't want to look for excuses but that's how it is. I'm not sure what the FA has to do in a situation like this but I will have to wait."
To add fuel to the fire, Silva hit back and insisted Klopp did not apologise to him for his passionate celebrations as he branded Liverpool “lucky, lucky, lucky”.
Silva said post-match: “No, he didn't apologise to me, All of your colleagues asked me about this situation but, to be honest, I didn't see what happened."
An £8,000 fine followed for Klopp after being charged for misconduct by the FA, but he had happily accepted his fate following the manic celebrations at Anfield that night.
“Absolutely OK, to be honest," he said in reflection. "I couldn’t avoid it obviously, but that’s what the rules are for, and if you break rules you have to be fined for it.”
The action even called for some remarkable calls for Klopp to be arrested by ex-Man City man Danny Mills: "To run into the middle of the pitch - if that's a fan, of course (he would get arrested). I think it's disrespectful to Everton, and he knows it."
Regardless, the victory gave Liverpool the belief needed to know they can win even when the clock is up, something they proved time and time again before going on to win their sixth Champions League in June.
That Everton goal was also the first of many 'Origi moments' that season with his double in the Champions League semi-final against Barcelona and his winner in the final - cult hero then legend personified.
The belief was firmly instilled into the Liverpool side that they could overcome any adversity and Origi's header in the 96th minute was firm evidence of that.
This Liverpool side had belief that they could overcome any adversity - Origi's header in the 96th minute against Everton was the start of it.
