Jurgen Klopp praised his assistant Peter Krawietz and Liverpool's analysts for Roberto Firmino's excellent goal against Inter Milan on Wednesday evening.
The Brazil international produced a superb glancing header at the near post from Andy Robertson's corner to give the Reds a vital 75th minute lead in the San Siro.
Mohamed Salah went on to score a late deflected strike to hand Liverpool a 2-0 advantage heading into the second leg at Anfield next month.
Yet it was Firmino's goal that proved crucial and Klopp was keen to highlight the work of Krawietz and his team's analysts, who devised the set-piece plan.
"Pete Krawietz and our analysts are responsible for that," admitted the Liverpool boss.

"When we do the analysis, we obviously see how the opponent is defending - everybody is doing that - and we didn’t have a lot of time to train.
"But yes we trained set-pieces yesterday. That was the only proper thing we did in training; a bit of tactical stuff.
"But without intensity and set-pieces you cannot train without intensity because one has to shoot and the other guys have to run. So, yes, it's all credit to Pete and his boys."
Krawietz previously worked with Klopp at German side Borussia Dortmund and took charge of their FA Cup tie against Shrewsbury Town last month.
Wednesday's game was in the balance before Firmino's opener and Virgil van Dijk, who produced an excellent defensive display, believes the goal hampered Inter's momentum.
"Yeah, but it’s normal," said the Dutchman when asked about the importance of the goal.
"You try everything and they did very well, I must say, defensively. It was very difficult to beat your marker but we found the space and [got] this great goal.
"In the end I think it’s a well deserved win of course, in my opinion, but it was very hard work and it will be the same in Liverpool."
The second leg of the last 16 tie takes place at Anfield on Tuesday, March 8.
Speaking to BT Sport after the game, Rio Ferdinand praised Van Dijk and fellow centre-back Ibrahima Konate for producing a brilliant partnership in the San Siro.
"I think 2-0 probably flatters them," claimed the former Manchester United captain.
"But the bedrock of most performances away from home in this stage of the Champions League is a good defence and today that was true for Liverpool.
"The two centre-backs were immense, Fabinho too. You have to weather storms in games.
"They had long spells where they were under the cosh but they have that experience to navigate through games and wait for the opportunities that they got."
Van Dijk will feel particularly vindicated with his display because, speaking before the game, Paolo Di Canio questioned his form since his return from a serious knee injury.
The centre-back ruptured an anterior cruciate ligament (ACL) against Everton in October 2020 and went on to miss the rest of last season.
"Since returning from injury, he’s not the same player and therefore the whole team concedes more," claimed Di Canio.
The Italian went on to say: "If you also look at Van Dijk’s body language, he used to move his arms to bring the full-backs tighter, but now he just flails his arms, complaining."
