Afterwards he told Sky Sports: “My feeling is mixed between being proud of my team for coming back in the second-half and being disappointed with the first-half.
“We didn’t respect the game-plan from the coach and we conceded three goals. This is not what we wanted.”
Arteta said his side’s first-half performance was “unacceptable”
“I am very disappointed because I cannot accept my team to play the way we did in certain periods in the first half,” the Gunners boss said.
“The goals we conceded. Because what I expect is the team to play the level that we showed afterwards. We played incredibly well, we should have scored six or seven goals.
“But we have two phases. The first phase is about giving goals to the opponent and not doing what we have to do. It’s not good enough.”
