<p>Arsenal manager Mikel Arteta admitted he was "in shock" after his side were outclassed in a 3-0 home defeat by Liverpool in the Premier League on Saturday.</p>.<p>Arteta's side barely laid a glove on the visitors and were undone by two second-half goals by Diogo Jota and one by Mohamed Salah, although the margin of defeat could have been bigger.</p>.<p>It left Arsenal down in ninth spot and Arteta with much to ponder after his 50th league game in charge produced a display he described as one of the worst in his tenure.</p>.<p>"We completely deserved to lose the game. They were better in every department and deserved to win the game with the margin they had, or even more," the Spaniard said.</p>.<p>"I accept responsibility for the way we played today. It is my fault. I have to set the team up to perform in a different way and that is it. At the moment I am in shock.</p>.<p>"I didn't expect that because of the way the team trained. It is a challenge. A challenge brings an opportunity. If you have courage and you represent a club like this, you have to stand up and take it."</p>.<p>Arteta's win percentage in the league from his first 50 games in charge is only 42%, compared to his predecessor Unai Emery's 49% from his 51 games at the helm.</p>.<p>While Arsenal have improved defensively under Arteta, the attacking flair they were once known for has been replaced by a cautious and often timid approach that was painfully evident against Liverpool.</p>.<p>"I don't know if it was the worst but probably one of the worst," Arteta said of the performance.</p>.<p>"We gave every ball away we could not put three passes together. There were too many simple things not done right. The basics weren't there today.</p>.<p>"We want to apologise, to our people and our fans. This is nowhere near what we want and we have to do better."</p>
