Origi added a second to Andy Robertson’s opener as Klopp’s title-chasing side fought through a frustrating challenge at Anfield.
Telling contributions in fleeting appearances have been Origi’s forte throughout his time at Liverpool.
His 95th-minute winner against Everton in 2018 had Klopp sprinting across the pitch in celebration, while he also scored a game-clinching second in the 2019 Champions League final, as well as a double in Liverpool’s famous 4-0 win over Barcelona that season.
He has saved his best for Liverpool’s bitter rivals Everton, with his late header after coming off the bench at Anfield on Sunday putting the seal on his team’s 2-0 win in a hard-fought Merseyside derby.
It was the 27-year-old’s sixth career goal against Everton, at least twice as many as he has managed against any other opponent in his Liverpool career, while he has now scored 11 goals as a substitute in the Premier League, the outright most by a Liverpool player.
“We are happy with the impact (from substitutes) all season,” Klopp said. “They come on with the right mindset when they come on. Luis (Diaz) and Divock were involved in the goals and that helps in tight football games.
“We did not show up there in the first half. We had a lot of possession, the most of a Premier League game for us (over 86%), but we changed things in the second half.
“He (Origi) is a legend on and off the pitch. Fantastic footballer, a world class striker and is our best finisher. Everyone would say the same. You see this in training. It is a really hard decision to make to leave him out. Everyone loves Divock here.”
His late winner in Liverpool’s 1-0 win at Wolverhampton Wanderers earlier this season, a match where Klopp’s side had struggled to break down their determined hosts, is just another example of his impact.
It could have all been so different at Anfield, had Everton been awarded a penalty when Anthony Gordon went down under a challenge from Joel Matip in the second half with the score at 0-0, a decision that infuriated coach Frank Lampard.
“It was a penalty,” Lampard said. “I don’t think you get them here. I think if that is Mo Salah at the other end, he gets the penalty.
“I am not trying to create conflict there, I just think it is the reality of football sometimes.”
But it was not to be, with Origi stepping off the bench to help create the first Liverpool goal for Robertson, before then putting the game to bed with yet another late strike.
