Arsenal manager Unai Emery has accepted responsibility for his team's second-half collapse against Watford last weekend.
Two goals from Pierre-Emerick Aubameyang gave the Gunners a 2-0 lead at the midway point of their recent trip to Vicarage Road.
Watford, who are still without a win in the Premier League this season following Saturday's 8-0 thrashing by Manchester City, fought back after the break to secure a 2-2 draw.
Sokratis Papastathopoulos’ mistake allowed Tom Cleverley to halve the deficit, before Roberto Pereyra scored from the penalty spot after a foul by David Luiz.
The Hornets were vastly superior throughout the second period, and ended the game having taken 31 shots - the most Arsenal have conceded in a top-flight match since Opta began collecting such data in 2003/04.
And Emery has admitted that he was the man to blame for Arsenal’s failure to pick up all three points in Hertfordshire last time out.
“One mistake is not his mistake,” he said when asked if Sokratis was left out of the squad that beat Eintracht Frankfurt 3-0 in the Europa League on Thursday because of his error last weekend.
“It is the mistake of all the team, and I am responsible because I decided to start like that.
“In the first 45 minutes they didn’t push a lot or do a really big press against us. We controlled the match with the ball, the possession, the build-up, easier in the first half. The second half changed because they needed to push more, to attack more, to go against us.”
