Arsenal manager Unai Emery has taken responsibility for Sunday's draw with Watford.
The Gunners blew a two-goal lead at Vicarage Road, with Tom Cleverley taking advantage of a comical error by Sokratis.
"We have some young players and they need to have experiences like today," he told a media conference.
"Matteo [Guendouzi] is young and very emotional; sometimes he needs to make some mistakes to improve. In the first half he made a mistake and they didn't score.
"When we are analysing the mistakes, we prefer to speak about them collectively. I have responsibility.
"I don't want to say it's the fault of one player or another. It's my responsibility to give them the confidence to execute our game plan."
