Thomas Partey has called on his team-mates to "learn from the mistakes" that they made as a team in the first half at West Ham United.
The hosts raced into a three-goal lead before we established ourselves in the game, although we dominated from that point on to fight back and claim a draw.
So what did Partey make of the performance overall?
"I think we could have done better from the beginning," he told Arsenal.com. "They dominated from the beginning and we were completely lost.
"I think they came out very strong. They overloaded us on the outside and they are strong with crossing. We allowed them too much time with the crossing and that hurt us a lot. Second half, we made sure we blocked all the crosses. From there we started to dominate.
"We stuck to our plan. We know how to hurt them, we went all-out and everybody was fighting as a team. I think the spirit was high after we conceded three goals. From there, we started to give our all. But we have to start as we ended, in both halves.
"I think we have to learn from all these mistakes, we have to know when we have to go out strong, when we have to dominate from the beginning. It's important in the Premier League to start winning from the beginning to be in the top. You have to start good and end well."
