Liverpool turned on the style to thrash Arsenal 3-0 and move into fifth place in the Premier League on Saturday with Diogo Jota netting twice after coming on as a substitute.
While their title is heading to Manchester City, the outgoing champions produced the kind of display that saw them romp to glory last season, albeit against a timid Arsenal.
The only surprise was that it took them until after halftime to make their superiority count.
Jota headed Liverpool in front from Trent Alexander-Arnold’s cross in the 64th minute, three minutes after coming on.
Mohamed Salah doubled Liverpool’s lead four minutes later before Jota scored from close range in the 81st minute.
Victory moved Liverpool above Tottenham Hotspur and West Ham United and left them only two points behind fourth-placed Chelsea who were thrashed at home by West Bromwich Albion earlier.
“Congratulations to Liverpool because they were exceptional today,” said Arteta.
“They can play at that level and we saw the difference today between the two teams when we play at that level. The margin is incredibly high.
“The standard has to be much higher for this football club.”
The Spaniard assumed responsibility for defeat, but called on his players to respond quickly to save their season in midweek.
“At the moment I am in shock,” added Arteta. “Now is a challenge and a challenge brings an opportunity.”
“If you represent a club like this you have to stand up in the next game and take it.”
“We don’t look at Chelsea or whatever because we have to win our own games, but in our situation other teams have to lose games as well,” said Liverpool boss Jurgen Klopp.
“We have to keep working, but it is a nice sign. We are still there. Tonight the package was extremely good.”
Liverpool have 49 points from 30 games with Arsenal down in ninth place with 42 points after a 12th defeat of the season.
