Sadio Mane and Mohamed Salah are a key reason why Liverpool have been so dangerous in attack for the past few seasons.

Both players' best attribute is the pace they have at their possession.

It is this skill that makes them such a nightmare to defend against and enables them to turn defence into attack in a blink of an eye.

They have displayed this against many teams; including when they combined to score against West Ham last campaign.

The two produced an outrageous counter-attack that resulted in Mane setting up Salah to notch Liverpool's first goal of the game.

Jurgen Klopp's side would go on to score three more times in a 4-1 win at the Olympic Stadium but it was this goal that topped the lot.

Liverpool remembered that goal by reposting on Instagram yesterday to celebrate its one year anniversary.

The video was accompanied by a caption that reads: "Pure pace from @mosalah and @sadiomaneofficiel ⚡️⚡️ #OnThisDay one year ago... 🌪 #LFC #LiverpoolFC #PremierLeague" 

That really was a lightning quick counter-attack and shows Mane and Salah at their very best.

Alex Oxlade-Chamberlain saw the goal and he made a funny comment in response.

The Ox was also on the pitch at the time of the goal and could be seen trying desperately to catch up with the two speedsters.

He eventually caught up with them but by the time he did Salah had already put the ball in the back of the net.

The caption for the video praised Mane and Salah's pace but not Oxlade-Chamberlain's; and he felt the need to make a light hearted dig at his team.

He wrote: @Liverpoolfc Sadio, Mo and... are you forgetting that 3rd runner that came from deep there...?!"

Gold. It's good to see The Ox is retaining his sense of humour while he continues his stint on the sidelines.

Oxlade-Chamberlain sustained multiple knee ligament damage against Roma at the back end of last season and is expected to miss the majority of the 2018/2019 campaign.

He provided a positive update about his recovery in September.

“It’s going well - very boring, very slow, very long, all the good stuff!" he told Liverpoolfc.com. "But I’m making progress, which is obviously what we need.

"It’s just a long process and I just keep plugging away, but I’m in good spirits and I’m really positive about it,” the England international said.

“You just get into a routine [with] tunnel vision and keep going, setting yourself little goals and little things to achieve.

“I passed the ball the other day, not very well, but I started passing the ball and that was massive for me to be able to kick and know that my knee can kick a ball.

“Even though it was five yards, I’ve started working on stuff like that and it’s little wins like that that keep you going and keep you pushing forward to the next one.”
