Arsenal fullback Sagna: We let ourselves down
AZ were able to snatch an injury-time equaliser in the Champions League clash and Sagna told arsenal.com: "Yes it does but we have to stay focused until the end of the game and we have to learn.
"Tonight we switched off because we thought maybe that the game was over and they scored a nice goal.
"With injury time, we have to concentrate 95 minutes these days. Tonight we only concentrated for maybe 90 minutes so we just have to learn from it and take all the positives we can."
