Sadio Mane notched up his fifth goal of the season against Red Star Belgrade on Wednesday night.Liverpool were at their attacking best during large periods of the game, eventually drubbing the Serbians 4-0 with Mohamed Salah bagging a brace and Roberto Firmino also finding the net.It was Mane who put the cherry on top late on, though, putting an end to his mini goal drought after starting the season in fine scoring form.The Senegalese forward will have been feeling rather releived about his goal, too, having missed a penalty just minutes beforehand.Salah had taken a spot kick earlier in the game, but wasn't on the pitch when Liverpool were awarded a second and there was some debate about who would step up.

Liverpool's penalties vs Red Star

Firmino missed twice from 12 yards last season so removed himself from contention, yet Daniel Sturridge quickly went over to the spot.

The Englishman has taken penalties for the Liverpool in the past, but eventually allowed Mane to inherit the responsibility and see his effort spectacularly saved.

If you're going to miss a penalty, miss it like Mane because Milan Borjan made a brilliant save and the game was already won.

Why wasn't Fabinho on penalties?

However, it didn't stop Liverpool fans from raising questions about the penalty selection and it's a good job the result wasn't in the balance when Mane stepped up.

And while they didn't necessarily have a massive problem with Mane, Kopites were wondering: why wasn't Fabinho on penalty duties?

The Brazilian midfielder was on the pitch for both penalty kicks, was the official taker for Monaco and hadn't missed a spot kick in a competitive game for over a year.

So, it was natural that Liverpool fans were scratching their heads and there was plenty of reaction on Twitter. Check out the pick of the tweets below:

It's definitely something for Jurgen Klopp to consider this season.

Despite playing for a club boasting players such as Radamel Falcao, Thomas Lemar and Bernardo Silva, Fabinho was the go-to man and scored on a regular basis.

In fact, his record with Monaco stood at an enviable 19 goals from 20 penalties taken.

Liverpool fans have come to suspect that Fabinho's lack of involvement has emanated from his missed penalty against Torino in pre-season.

That, and his lack of game-time since joining Liverpool could have seen Klopp allocated the likes of Salah, Mane and Sturridge before him.

Fabinho can certainly expect to rise up the pecking order after Mane's miss, though, and his record suggests he could be a huge asset for Liverpool when the chips are down.

For all the solid defending and fluid attacking, one shot from 12 yards can hugely impact a season.
