But he refused to blame the kids, added: “If you look at the goals it’s not necessarily the defence that cost us.
“We are not stupid. We prepare well the players we have.
“But we have been unlucky a well by losing Mertesacker and Gabriel with injuries. We have to be ready next week because we go to Leicester.”
Wenger is under pressure to make signings, with some Arsenal fans already turning on him during the game.
He said: “I am always under pressure! We are working very hard to get one or two players in.
“I don’t know what you call desperate. Any signings need to make sense and be of quality.”
