Unai Emery took ultimate responsibility for Arsenal’s capitulation against Watford on Sunday but believes the experience could help his young players in the long term..”

The Gunners appeared to be coasting to all three points at Vicarage Road after Pierre Emerick-Aubameyang’s first-half double.

Tom Cleverley took advantage of some slapstick defending by Sokratis Papastathopoulos to reduce the deficit, however, before Roberto Pereyra ensured a share of the spoils from the penalty spot with nine minutes remaining after he had been brought down by David Luiz.

The Hornets – who had 31 shots on goal – can consider themselves unlucky not have claimed all three points, leaving Emery to hope the chastening experience will be of use to some of his side’s younger players.

“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.”
