Arsenal boss Mikel Arteta admits they were completely outclassed by Liverpool on Saturday night.
The Reds won 3-0 in London as Diogo Jota (2) and Mohamed Salah struck for the visitors in the second-half.
Arteta said afterwards, "They were better in every department. I take the blame, it's my responsibility. They were the best team by far. They won by three goals and it could have been more.
"They won every duel, every second ball, every challenge. To be fair, I'm in shock. I didn't expect that one coming. It's my job to make things better. Today we hit a really low level. It was not acceptable.
"For sure we cannot hit that level again. When you represent this club you have to stand up and take the challenge."
