Wenger had named a side with an average age of only 19 - and was not disappointed as the youngsters stepped up to the challenge for a convincing Carling Cup win.

Mexican striker Carlos Vela grabbed a hat-trick, while Nicklas Bendtner hit a first-half double and 16-year-old Jack Wilshere weighed in with his first senior goal.

There were also impressive displays from Wales Under-21 midfielder Aaron Ramsey and aspiring full-back Kieran Gibbs, which all left the Arsenal manager confident the club's future is in safe hands.

He said: "The team showed a good mixture of talent and a mature collective spirit to play football the way we want to play.

"The way the team remained focused and they looked a complete team. I am very proud of that.

"We looked strong in every individual position, and that takes a lot of hard work."

Wenger added: "We knew about Bendtner, but we discovered more about Vela. He is a clinical finisher.

"I integrated Wilshere into the first team sometimes last season when he was 15 and he did not look out of place and it is natural for him.

"I was not surprised because I see them every day, but you never know on a big stage how they play.

"They did that with the belief we want them to have and the spirit we want then to have.

"Now for us the biggest challenge is to keep them together and slowly integrate them into the first team. Some have done that already.

"When you are under immense pressure to buy in every transfer window, when you know that you have these players behind it would be killing the work we have done."
