Trent Alexander-Arnold’s superb long-range strike made it three inside half an hour, before goals from Roberto Firmino and Virgil van Dijk meant Liverpool led by five at half-time.
After the break, one from Chris Mepham, another from Firmino, Liverpool’s first goal from Fabio Carvalho and another from Diaz rounded off a goal-filled afternoon for the hosts.
The record victory was achieved three times before by a nine-goal margin — twice against Manchester United and once against Leicester City — and helped kick off Liverpool’s torrid start to the new season.
As for Liverpool manager Jurgen Klopp, he called it “a great afternoon of football” after a poor couple of weeks, saying the big win was “necessary”.
“You just have to give the game a right direction and that’s why I liked the start today. We didn’t hesitate, we didn’t leave anything behind, we just went full in the game. Put under pressure, battles in the right areas in the box, around the box, bodies in the box, second ball situations, go again, and that sort of thing.”
After two trophies last season and coming close to two more, hopes are high for Liverpool this season.
And those flames were only fanned in the season-opening Community Shield against Manchester City, as Liverpool comfortably beat the reigning Premier League champions.
However, when the season finally began, the results were mixed.
It started against newly promoted Fulham before settling for a draw with Crystal Palace – star new signing Darwin Nunes was also sent off for a headbutt on Crystal Palace defender Joachim Anderson on his home debut. .
And things went from bad to worse in their third game with a stunning 2-1 defeat to Manchester United, their bitter rivals coming into the game on the back of a terrible start to the season.
Just when things seemed to be piling up, Liverpool responded in style.
Brazil international Firmino played a key role throughout the afternoon with two goals and three assists. Klopp said the 30-year-old played a “massive game” against Bournemouth.
Liverpool scored five goals in the opening 45 minutes in the first half to put the club first, the first time this has happened in a Premier League game for the Reds.
In reaching the nine-goal winning margin, Liverpool equaled the records set by Manchester United against Ipswich in 1995 and against Southampton last year, and Leicester against Southampton in 2019.
According to Opta, it also equaled Liverpool’s biggest margin of victory in their league history, equaling the records set against Crystal Palace in 1989 and Rotherham Town in 1896.
After a disappointing result against Manchester United last time out, Klopp was delighted with his side’s ability to bounce back strongly against Bournemouth.
“This game was us, a bit more us. We should have won this game, so while I won’t say that about all the games against United… we lost against them in different circumstances,” he said. ” They said.
Klopp continued: “But it’s not out of this world that we lose 2-1 at United, especially when we’re not at our best, it could happen and it’s very likely to happen. “For today, I wanted to start with what we showed. And then the rest… We can’t guarantee results, but what we expect from ourselves is that we guarantee the level of performance and today. We started.
