Any relegation fears still lingering Watford fans? Or do you just write off these away games at the top clubs?

Joel: I want tonight to be that night Mo Salah gets his first hat-trick in English Football. He has been awesome, exceptional, breathtaking.

Does being brought off now mean you can sneak off for a hot shower before the rest of the lads? Or would you tough it out on the bench? Tricky decision.

Watford make their second change first, Troy Deeney wandering off to be replaced by Stefan Okaka.

Then it's Liverpool's turn as Gini Wijnaldum sees his number go up. Alex Oxlade-Chamberlain is on for the final 20.

Plenty of activity on the touchline, both managers are keeping the fourth official busy. Time for a couple more changes...

Watford keeper Orestis Karnezis needs his wits about him, racing out to boot clear a Adrian Mariappa backpass with Mo Salah haring into his eye-line.

Not much to report at the moment. Watford still working hard after that tactical reshuffle, but don't look like penetrating the Liverpool defence.

Yep, off goes Richarlison and he is replaced by Will Hughes. You'd imagine Hughes would drop in to the middle and there'd be a tactical reshuffle from Gracia.

Javi Gracia is stood motionless on the Anfield touchline, carefully wrapped up in puffa jacket, snood and beanie hat. The Spaniard looks colder than a snowman.

Is he going to change something soon?

Another chance for Roberto Firmino as he meets Joe Gomez's right-wing cross. Watford keeper Orestis Karnezis breathes a sigh of relief as it drifts wide.

Johnny: What a game Mané is having. His passing and vision in particular have been exceptional today.

Eston: In a market where Mendy costs £60m, you can get Robertson for £8m. What a day light robbery! He's never switched off since his debut, bossing every game.

Roberto Firmino is grooving now. The Liverpool forward turns sharply in the Watford box, Cruyff like, as Adrian Mariappa nearly gets sent the wrong way. He recovers to block the cross... was there a hand involved? Firmino thinks so, the ref says no.

A few ironic 'Oles!' as Watford string a few passes together around the halfway mark. Not sure if that from the home fans or the away ones...

Roberto Firmino is a fantastic player. Such a talent in the way he reads the game. His decision-making is always on point; he works hard for the team but creates as well. He’s not a natural number nine. but brings everything together for Liverpool.

Watford will be sick of the sight of Roberto Firmino's bright white smile.

The Brazil forward has had a hand in seven goals in his last five Premier League games against Watford - four goals, three assists.

Hang on, Watford aren't going down without a fight. The visitors manage a jab back, Roberto Pereyra's dipping free-kick clipping the top of the Liverpool crossbar.

James: I think Watford should just bring that bus you mentioned onto the pitch and park it. This could be four or five nil.

Andy Robertson and Mo Salah are more in tune than Lennon and McCartney. Left-back Robertson looks up inside his own half and pings a 50-yard diag towards Salah. His touch, for once, let's him down.
