Arsenal boss Mikel Arteta says a pass from Virgil van Dijk was key to Liverpool's victory last night.
It was a moment during the game when Van Dijk played in teammate Mohamed Salah from defence that most impressed Arteta.
He said: "We tried to put them under as much pressure as we could but Van Dijk plays 60 yards to Salah and they are out.
"This is real quality and that is why they have spent the money they have."
"We are on a different journey to them. They have been together for five years, they have a lot of belief and great recruitment while improving the players they have.
"They have set the bar for highest it has been in Premier League for many years."
