Arsenal boss Arsene Wenger had no complaints after their 2-2 draw with Hull City.
Danny Welbeck saved Arsenal's blushes with an injury time equaliser.
"We got a point but we had 80 per cent possession. It is a very disappointing result," said Wenger.
"We were unlucky with the referee on the first goal, but on the second goal we can only blame ourselves.
"We came out of the dressing room with a lack of focus and gave them the lead straight away. It was difficult.
"I cannot fault the effort or the heart that we had in the game. The defensive concentration was missing on the second goal and when you make it difficult at that level you cannot give the goals away like that."
Wenger added: "Even in the last five minutes we had three clear-cut chances on goal. It is difficult when we play against teams who are physically stronger and organised, it was 10 against 10 in one half.
"This was the kind of game where we couldn't afford to concede another goal when we came out at 1-1. We know that - we have enough experience to know that and we cannot give a goal away like we did.
"But we put our heart and effort in until the last second and I cannot fault the effort, the spirit and the work rate of the team."
