It's goodbye from him, and it's goodbye from me.

But the football fun doesn't end there. Oh no.

Head over to this page where you can follow Manchester United against Brighton in the FA Cup quarter-finals. This is football heritage.

Well... what a night for Mo Salah. What a night for Liverpool.

You want to relive it again Reds fans? Have a gander at our match report by Emma Sanders.

Watford fans, if any of you are still with us, we'll forgive you if want to swerve it...

• Mohamed Salah has scored 36 goals for Liverpool in all competitions – the most by a single player in their debut season for the Reds
• Salah has scored 28 Premier League goals this season, only one African player has netted more in a single campaign (Didier Drogba 29 in 2009-10)
• Salah is the first Egyptian player to score a Premier League hat-trick, with Egypt the 43rd nation overall and the 10th African country to provide a hat-trick scorer in the competition
• Salah scored four goals from his four shots - the first player to do so in the Premier League since Andrey Arshavin in April 2009, also at Anfield
• Roberto Firmino (3 assists) and Mo Salah (4 assists) have combined for seven goals in the Premier League this season – the joint-most by any duo, level with Sadio Mane (6 assists) and Mo Salah (1 assist)

Mo Salah was soooo good today, we're even giving him his own stats section...

• This was Jurgen Klopp’s 50th Premier League home game in charge of Liverpool - he has won 28, drawn 18 and lost four
• The Reds have averaged 2.20 goals per game since Klopp took over – their highest goals per game ratio at Anfield in the competition under any manager
• Watford have lost 10 of their 11 top-flight away games against Liverpool, winning only in August 1999 on what was the Hornets’ first visit in the Premier League
• Sadio Mane has had a hand in five goals in three Premier League games against Watford for Liverpool (three goals, two assists)
• Watford are winless in their last nine Premier League away games (D1 L8), scoring just twice in that run and failing to find the net in each of the last five

As you may know, it's currently Sport Relief week and the goal is to get people across the nation to do a combined billion steps per day.

Fans can download the Sport Relief app and join a variety of mini leagues - one with all your mates, one with fellow Harry Potter fans etc. There's a Premier League league (if you catch the drift) where you pledge your allegiance to your football club and your steps count for your club. Download the Sport Relief app - that's NOT the BBC Sport app (very important).

Read here for more info.

And talking about Relief...

More from Reds boss Jurgen Klopp: "In sport, you always need to strike back against the next opponent and that's what we tried to do. We take it really seriously.

"There were a few things we needed to work on, but it was clear it was going to be a totally different game tonight. It's a big relief, I'm really happy.

"For Mo [Salah] to be involved in five goals is fantastic but to score four is even more fantastic.

"His goals are so important for us. We have to hope they all come back well from the internationals.

"The clean sheet is very important. They lost a little concentration in the last few minutes but that's normal. It helps us in the goal difference."

Liverpool

Liverpool manager Jurgen Klopp, speaking to BBC Match of the Day: "It was very pleasing. It could have been really difficult tonight.

"We knew we had to be spot on from the first to the last second and our work rate had to be higher than 100%.

"The goals we scored were unbelievably good, and the boys didn't stop. That's how football should be, so I'm really happy with the performance."

These two fellas knew a thing or two about scoring goals...

Liverpool

Liverpool defender Andrew Robertson, speaking to BBC Match of the Day: "It was brilliant. We got off to a fast start which was crucial to this game. We were dominant throughout.

"Last week was a huge disappointment but we've used this week to forget about it. We knew it was a big game and it's a big three points going into the international break.

"Mo [Salah] keeps on scoring, and what he's doing this season is phenomenal.

"It's massive for us to get a clean sheet."

Watford

Watford manager Javi Gracia, speaking to BBC Match of the Day: "We knew today was going to be a tough game. It was difficult.

"We conceded an early goal again like we did against Arsenal and after that it was difficult. We will try to do better next time.

"It was a very tough game for us, they were much better than us and congratulations to them.

"We tried to be stronger in defence.Mo Salah is one of the best players at the moment. We know we have played against one of the best teams in Europe.

"There are positives we can take, but we will try to do better next time."

Watford

Watford manager Javi Gracia, speaking to BT Sport: "Playing against Liverpool is always difficult. They are very good and if you concede an early goal, it's very difficult. We tried, but they were much better.

"We know we need to improve our performances away from home but we are focusing on the next two home games. We would like to be better then with the support of our fans.

"We know we need to improve, but you need time to build up a better team. We have time over the next two weeks to improve.

"We need to get points as soon as possible. We will work hard."

Watford

Watford defender Adrian Mariappa: "It was a real tough day for the whole team - 5-0 is a pretty embarrassing scoreline.

"Poor defending on the whole from us, losing ball in key areas and they really capitalised on those mistakes.

"They are a good side with so much quality and we got punished. Today Salah was on it and he punished us. We will have to look at all the goals, like we usually do, and move onto the next game."

Absolutely clinical from Mo Salah. He only had four shots at the Watford goal today. That's all he needed...

Liverpool

Liverpool's four-goal hero Mo Salah, who has scored now scored 36 times this season, speaking to BT Sport: "I have to thank everyone but mainly my team-mates, without them I couldn't reach this number.

"Each game we try to win the three points, but every game I want to score and help the team. But today the most important thing is three points.

"We showed a god reaction after the last game. We had a good result and clean sheet - that's most important."

All very humble from Mo Salah in his post-match interview. Thanking his team-mates, saying points are the most important thing, etc, etc. He's as calm and composed in front of the cameras as he is in the penalty box...

Isaac: Salah, has to be, been the most consistent out the 2 and isn't surrounded by the team like De Bruyne has at city

Jared: Salah, no contest.
