Arsene Wenger is refusing to blame keeper Manuel Almunia for Arsenal's shock 3-2 home defeat to West Brom on Saturday.
The Baggies pulled off the shock of the season so far with a remarkable league success at Emirates Stadium.
Although Almunia saved Chris Brunt's penalty after initially conceding the spot-kick, he was at fault for Gonzalo Jara's goal by spilling his near-post effort.
Jerome Thomas made it 3-0 to the visitors and while Samir Nasri set up a tense finish with a brace West Brom held on for a fully-deserved famous success.
Wenger insists the whole team are to blame for the disappointing result and that Almunia was not the sole reason behind their first league defeat this season.
Team to blame
"I don't think it was down to one player," said Wenger. "I think our level of focus on the job was not right.
"I believe you can include all the defenders as well. They all made massive mistakes so it would not be right to blame one player more than any other.
"We came back, we didn't give up and that was the positive. We fought until the last second but we started too late and we have to learn from what happened.
"We cannot repeat that kind of performance."
