Mohamed Salah extended his brilliant run of form with the winning goal against Napoli on Tuedsay night.
Fresh from scoring a hat-trick at Bournemouth over the weekend, the Egyptian delivered once again with a strike that secured Liverpool's place in the Champions League knockout stages.
It was a huge match for the Reds who had lost all their away games in Europe and needed to defeat their Italian opponents 1-0 or by two clear goals.
Thankfully, there weren't too many nerves around Anfield as Salah's goal came during the first-half, beating David Ospina at the near post.
The Colombian should have done much better with the shot, but it was the build-up from Salah that received so much praise and particularly his ability to breeze right past Kalidou Koulibaly.
Salah's winner vs Napoli
Regarded as one of the best centre-backs in the world, he was left flat-footed in the penalty area as Salah passed him and relegated Napoli to the Europa League.
Interestingly, though, there was still widespread praise for Koulibaly's performance and Manchester United fans were calling for Jose Mourinho to sign him on Twitter.
It's credit to his showing that Salah's skill didn't overshadow it and a video of the pair's clash has emerged in the aftermath of the game.
Salah vs Koulibaly
With Salah playing out on the right, they came into contact regularly and, as a result, there is almost two minute's worth of footage of them going head-to-head.
It certainly makes interesting watching and actually shows that Koulibaly was winning the battle for most of the game, using his strength and pace against the Egyptian.
However, it's that one piece of skill that catches out the defender and wins the game, showing that you can't take your eye off Salah for one second.
Check out the clip below:
It goes to show top defenders around the world, you can go 89 minutes with Salah in your back-pocket but he can change a game with one piece of skill.
It's credit to Salah that Koulibaly dealt with him better than most defenders this season, yet the abiding memory was still him gliding forward to score.
Nevertheless, Premier League defenders can still learn a lot from Koulibaly's performance, drawing on the vast positives and also learning from his crucial mistake.
Salah, like many of the best players in the world, are capable of pouncing upon a single lapse in concentration or smallest of mistakes.
In this case, it saw Liverpool quality for the round of 16 and they'll be hoping for another appearance in the final after last season's journey.
The goals of Salah will be crucial to any run in Europe, but this week goes to show that even the world's elite defenders have their hands full playing against him.
