Watford 2-3 Liverpool
Mohamed Salah sniffing a second.
The first part is excellent, chesting down the ball on the edge of the box, but the second part is not so, lashing a left-footed drive over the crossbar.

Mohamed Salah sniffing a second.
The first part is excellent, chesting down the ball on the edge of the box, but the second part is not so, lashing a left-footed drive over the crossbar.
Watford 2-3 Liverpool
Youngster Trent Alexander-Arnold has been given the responsibility at set-pieces.
He plays in a brilliant corner to the front post, which Dejan Lovren heads towards goal, but Heurelho Gomes flings himself to his right to push the ball away.
What an eventful game this has been and there are definitely more goals in it.

Watford 2-3 Liverpool
Jose Holebas himself swings in the free-kick, but Liverpool manage to clear.
Watford 2-3 Liverpool
Jose Holebas is is getting kicked form pillar to post by a couple of Liverpool players on the left flank and rightly earns a free-kick in a dangerous position...

Thrilling encounter so far and it has been heading Liverpool's way since half-time.

It's looking very tough for Watford - they seem to have gone to pieces since falling behind, while Liverpool look rampant and likely to score more.

Mark Ryan: The nervous disposition of Liverpool fans tested again. Emotional roller coaster to say the least.
Daniel Woodley: New season but the same old Heurelho Gomes. Has gifted Liverpool two goals in quick succession. Such awful decision making.
John Louis: 145 minutes into the Premier League and there's already 10+ goals. This is why we love English football.

Watford 2-3 Liverpool
Almost a fourth for the visitors.
Joel Matip flicks on Roberto Firmino's corner - with his back - and it cannons off the crossbar.
No Liverpool player can gobble up the rebound.
Watford 2-3 Liverpool
From looking assured early on, the Watford defence now looks as good as Liverpool's.
Alberto Moreno pinches the ball ahead of Jose Holebas and lets fly with a left-footed drive which Heurelho Gomes tips over the bar.
Corner.
Watford 2-3 Liverpool
Watford's club record signing Andre Gray is coming on.
Boss Marco Silva has pointed his finger to the striker and told him, "you're the bad man."
He replaces Stefano Okaka and the Liverpool defence will be pleased to see the back of him.
Watford 2-3 Liverpool
Too eager to get the ball, Trent Alexander-Arnold chops Richarlison from behind and earns a booking.
Watford 2-3 Liverpool
He has scored one, but Mohamed Salah could have had a hat-trick in this match.
He is played through on goal by Trent Alexander-Arnold and tries to stab an effort at goal, but cannot get enough on it and Heurelho Gomes collects.

Sir Fabian Perez: Ohhh Dear. A goals galore in two matches with Pep Guardiola's City yet to play. Welcome Back.

Daniel Okeke: Mo Salah so much needed that confidence booster goal

Britos got it horribly wrong at the back for Watford - he wasn't looking across his own line and played Firmino on.
And it was great, unselfish centre-forward play from Firmino, who was through on his own in a good position but expertly chipped it across for Salah to finish.
Watford 2-3 Liverpool
Mohamed Salah is the 12th different player to score on his Premier League debut for Liverpool.
Can you name the others?

Ahead twice, now the Hornets are behind. What are they made of?
Mohamed Salah
Two in two minutes, Liverpool turn the game around.
Brilliant stuff from the Reds.
Roberto Firmino takes down Dejan Lovren's long ball and knocks the ball over the onrushing Heurelho Gomes.
It is about to nestle in at the back post, but new signing Mohamed Salah makes sure by thrashing the ball in from all of two yards out.
A nice easy way for the Egyptian to get off the mark and start paying off that £34m.

Danny Mills
Ex-Man City and England defender on 5 live Sport
A blatant penalty. Perhaps Gomes just judged it wrong, after being quite slow to come off his line. And that was a superbly taken penalty.
Roberto Firmino
No mistake.
Heurelho Gomes goes left, Roberto Firmino goes right, drilling his penalty low and into the bottom corner.
Coolly done and Liverpool are level.
