Liverpool maintained their unbeaten start to the Premier League season with a 3-0 victory over Watford.Although on paper it seems like Liverpool enjoyed an easy afternoon, that is far from the truth.Watford put in a spirited display and frustrated their opponents for the large majority of the match.The two sides went into half-time level and, it was only until Mo Salah opened the scoring in the 67th minute that Liverpool ran away with it.Further goals from Trent Alexander-Arnold and Roberto Firmino ensured they would take all three points back to Merseyside.In the end, it was a good day for Liverpool, and especially Firmino.The Brazilian striker has gone through a barren spell in front of goal, with his last goal in the Premier League coming way back in September against Tottenham.But he ended that run by converting an impressive counter-attack with just a minute to play.Many fans had criticised his performances, thinking he should have been dropped, but he turned in an impressive display against Watford.Although he scored, the highlight of his game came when he conjured up a wonderful piece of skill to make Troy Deeney look silly.With three players surrounding him, Firmino produced a wonderful turn which went through Deeney's legs.

That's pure class from Firmino.

A lot of people have been berating the Brazilian forward for his bad run of form, but he showed he was getting back to his best against Watford.

Jurgen Klopp was happy with how his side performed in the win.

"It was a really mature performance," he said after the game, per Liverpoolfc.com. "I am not sure if we had the ball in the past when we’ve played here, they were much more open games – especially the 3-3 we played here.

"We’ve never controlled games like this in the manner we do it now. I like that.

"It was 3-0 and I don’t think any Liverpool supporter wants another result or another performance.

"It’s just exactly how it had be in our situation because we have to win football games week in, week out. I am really happy about the way [we did it]."
