For 75 minutes it looked as though Liverpool were heading towards a bore draw against Sunderland at Anfield on Saturday.
Try as they might, the Reds were unable to fire past Jordan Pickford despite enjoying 78% possession and recording 27 attempts on goal.
It was ultimately a substitute who turned the game on its head, with Divock Origi scoring 15 minutes from time having replaced Philippe Coutinho in the first half.

From Jordan Henderson's pass, the Belgian cut inside and curled a delightful strike into the far-right corner to send Anfield into raptures.
James Milner would later secure a comfortable 2-0 win from the penalty spot in stoppage time.

As time wore on, doubt will have undoubtedly started creeping into the minds of Liverpool's players, who couldn't force their way through a resilient Sunderland defence.
Sheer grit and determination eventually saw them break the deadlock - with a little bit of help from Jurgen Klopp and the club's supporters.
With just over an hour played, Klopp was caught on camera yelling at Liverpool's fans and waving his arms around in frustration (see below). Commentators thought he was angry with them for groaning at a poor pass from Henderson.
However, speaking ahead of Tuesday's EFL Cup clash against Leeds United, the German explained how he was merely trying to improve the atmosphere.
He said: "I have to do a job and the crowd need to do a job. Sometimes you need reminders in life.
"It was obviously easy as they were ready. It is better to play when the atmosphere is like this."
And sure enough, with Anfield rocking, Liverpool took the lead 12 minutes later.
Speaking after the game, Jamie Carragher hailed Klopp for his passion and explained how the former Mainz boss is one of few managers who can get away with such behaviour on the touchline.
"It depends on who you are, the results that you get and the Liverpool supporters love Jurgen Klopp, so he could basically do anything on the side of the pitch," he said.
"Everyone buys into it when he does it. With certain managers if the results weren’t going well and there wasn’t that sort of mutual admiration for the manager, it may just switch them off.
"But with Klopp he’s just got something about him that everyone buys into. The whole crowd believe in him. I think he's one of few managers in world football who could get away with that."
