To say Sadio Mane was in the mood against Watford would be putting things mildly.With Liverpool's advantage over Manchester City standing at a single point after the weekend's action, it was imperative that the Reds returned to winning aways at Anfield.The visit of Watford was never going to be the easiest fixture, despite their comfortable win last season, and especially when you consider their success under Javi Gracia this season.But they looked to take the game out of Liverpool's reach within a matter of minutes, Mane continuing his rich vein of form on Merseyside with a bullet header.It was thanks in no small part to Trent Alexander-Arnold, whipping in a superb cross from the right wing in a moment that drew wide praise form Kopites on Twitter.

Liverpool vs Watford

However, it would get even better for Mane and Liverpool just a few minutes later.

Starting from a herculean sprint from Mohamed Salah along the touchline, the home side managed to carve out another opportunity and Alexander-Arnold once again turned provider.

Mane found himself with acres of spaces in the penalty area but his back facing to goal and Ben Foster - who has been brilliant for Watford this season - closing him down.

Mane's audacious back-heel

Yet an inspired moment from Mane was enough to find the net, audaciously producing a back-heel to dig the ball into the Anfield turf, over Foster and between the posts.

It's one of the most unique and best goals of the season - check it out down below:

Sadio, take a bow.

Perhaps the only goal that can compare came from Dominic Solanke, who also used a back-heel as means of lobbing a goalkeeper for the England U21 side.

Mane has definitely topped that effort against Watford, though, and it will be replayed for years to come. Brilliant stuff.

At the time of writing, Liverpool lead the visitors 2-0 at half-time and should maintain their advantage at the Premier League summit.

Mane has been crucial for Jurgen Klopp's men in recent weeks, while Roberto Firmino and Salah have been experiencing a slight stagnation in form.

The Senegalese forward must be considered one of the league's best players on recent evidence and he seems particularly unstoppable on home soil.

Perhaps Klopp should consider playing him through the middle more often...
