Liverpool left it late again in a 2-1 win over Wolves with Roberto Firmino netting in the 84th minute to restore his team's 16-point lead in the table with a 14th straight Premier League victory on Thursday night.
Sadio Mane was taken off with an apparent injury and replaced just after the half-hour mark by new arrival Takumi Minamino, who was making his Premier League debut after signing from FC Salzburg in December.
Klopp said after the match: "It's probably a muscle, he felt something in the hamstring, we don't know yet."
Wolves, who have given Jurgen Klopp's side fits in recent meetings, grew into the match as the first half wore on, but the home side was unable to find an equaliser and Liverpool took a one-goal lead into half-time.
The hosts would get back on level terms soon after the restart from a quick-hitting counter-attack that finished with Raul Jimenez smashing a header past Alisson to the delight of the Molineux crowd.
Wolves were firmly on the front foot after the goal and would have been ahead were it not for a pair of stellar Alisson saves on shots from Adama Traore and Jimenez shortly after the equaliser.
Liverpool once again found their winner late in a match, this time when Firmino was played into the area by Henderson after some fancy footwork from Mohamed Salah and the Brazilian smashed his shot past Patricio to keep their winning streak alive.
Klopp punched the air at full-time and Liverpool fans sang "We shall not be moved" as the relentless Reds close in on their first top-flight title in thirty years.
"We had incredible chances in the first half and then at the end it was a magic moment from Bobby [Firmino]," said Klopp. "You just have to find a way to win and have someone who makes the perfect decision and that was Bobby again."
Henderson added: "You know it's going to be difficult here. They're a good team, they make you work. But we knew we could keep going, keep fighting."
The result keeps Liverpool 16 points ahead of Manchester City in the table and with a game in hand, while Wolves remain in seventh place on 34 points. It also extends the Reds unbeaten run to 40 matches, with 110 points over 35 wins and five draws during that stretch.
"Very good performance," said Wolves boss Nuno Espirito Santos, who was proud of his battling team even in defeat against a flying Liverpool side who conceded their first goal in eight league games.
"Defensively we were organised and we played good. We created chances and the momentum was there but we faced a very good team. I am very happy with the boys. Small margins."
Despite their massive lead in the table, though, both Klopp and Henderson refused to talk about the title, saying for now the team is just taking it one step at a time.
"I don't think about it [winning the title]. I just think about winning the next matches ... let's carry on," he said after Liverpool's 22nd victory in 23 league games this season.
"It's over when it's over, not before," added Klopp, saying he had forgotten during the week how many points Liverpool were on and was now purely focused in their next games at Shrewsbury Town in the FA Cup on Sunday (stream live at noon ET on ESPN+) and West Ham United in the Premier League.
Henderson said: "You're probably bored of me keeping saying it, but it's just about the next game, I want to keep going.
"Every game is the biggest game of the season as the manager keeps saying to us. We just want to keep going, give everything like we always do and keep building on what we've achieved so far."
