Theo Walcott admits an inability to consolidate a winning position has been a major failing of Arsenal this season. The Gunners failed to hold on to winning positions in their last two games against Tottenham and Liverpool.
Walcott also highlights the loss of their four-goal advantage at Newcastle as another low this campaign and the defeat to Spurs in the earlier derby this season.
"It has been a disappointment of this season," he told the Sunday Telegraph.
"You feel like you need to score three or four goals to win at times. The Newcastle game... it shouldn't happen, even if you go down to 10 men.
"If we want to be winning things, we can't let a lead like that slip. That's what we have been doing too much this season.
"We have had lots of disappointing results. Spurs beating us at home when we are 2-0 up was not good enough, especially for the fans because that's the one they look forward to all year.
"Hopefully we will learn from it. We have to. If we want to win trophies we need to learn straight away. We can't be using the excuse of being young players. We're experienced, we've played in the Champions League.
"We need to stand up for ourselves and take responsibility at times, and I'm not sure we are always doing that."
