Liverpool 4-3 Salzburg: Five talking points

Reds forward Sadio Mane began the scoring against his former club, Andy Robertson doubled the advantage at the end of a fine team move, and Salah put the home side 3-0 up after 36 minutes.

The visitors produced a remarkable fightback to level the score by the hour mark - but Salah struck his second goal of the match on 69 minutes to secure an important victory.

Here are five talking points from a dramatic Group E encounter...

Mane shows his class

Mane took just nine minutes to remind former club Salzburg of his goalscoring prowess - and the muted celebration that followed his strike reminded them of his class, too.

The Senegal forward scored 45 goals in 87 games during his two-and-a-half years at the Austrian club and helped them win the league and cup double in 2013-14.

In the pre-match press conference, he expressed his heartfelt gratitude to the side who helped establish him in the game before adding: "But at the same time, I would love to win against them."

True to his word, it was Mane's opening goal from Roberto Firmino's through-ball that set the Reds on the road to victory.

He also remained as combative as ever, battling out 18 duels while providing the joint-most key passes (three) with Firmino.

Fluid full-backs

If there was ever a moment to perfectly encapsulate the attacking intent of Liverpool's full-backs it came midway through the first half when Robertson and Trent Alexander-Arnold combined to seal a sweeping move and put their side 2-0 up.

Started and finished by Robertson, the left-back took possession inside his own half, drove forward, clipped the ball inside to Jordan Henderson and continued his purposeful run towards the opposition box.

Henderson played a quick one-two with Salah before picking out overlapping right-back Alexander-Arnold, who delivered a pinpoint cross for his defensive partner to steer home from six yards and notch his first ever Champions League goal.

It took just five passes from Robertson's marauding start to composed finish, with the full-backs the two most advanced players in a clinical attacking passage.

Tactical tweaks

After being pegged back to 3-3 by the impressive visitors on the hour mark, Jürgen Klopp responded with a double substitution and tactical change as James Milner and Divock Origi entered the fray.

On for Henderson and Georginio Wijnaldum, the switch in personnel was accompanied by a new formation.

The Reds changed to 4-2-3-1, with Milner dropping in alongside Fabinho at the base of midfield and Firmino playing in behind Salah.

By 69 minutes Klopp's men were back in front, Firmino flicking on Fabinho's lofted pass for Salah to deftly guide into the Kop-end net from 10 yards out.

Salah's impressive Anfield haul

Having also turned in the rebound from Firmino's header to score Liverpool's third of the evening, Salah notched his 11th and 12th Champions League goals in 13 matches at Anfield.

To put that into perspective, only Reds legend Steven Gerrard has scored more. However, the former skipper's 18 strikes came over 46 home games in the competition.

Salah's double against Salzburg came from just three shots on goal and his excellent conversion rate helped the hosts maintain their formidable streak at fortress Anfield.

Liverpool are now unbeaten in their last 23 home fixtures in European football - a run that stretches back to October 2014.

Group E up for grabs

With Genk holding Napoli to a 0-0 draw in the group's other game on matchday two, only one point now separates the top three teams.

Serie A side Napoli top the section ahead of second-placed Liverpool but Carlo Ancelotti's men, who beat the Reds in Italy last month, must still visit Anfield.

However, next up for Klopp's team is a trip to Belgium to face bottom club Genk in the first of a double-header.
