Arsenal boss Arsene Wenger has no idea why Chelsea cut loose new Gunners hero Eddie Nketiah.

The former Chelsea youth teamer scored twice to help Arsenal defeat Norwich City in the Carabao Cup last night.

Wenger said: "The fact is we needed to score goals and he can score goals.

"Overall in the end we had something like eight strikers on the pitch and I know he has the qualities but when a team needs you, you don't know how he will respond. He has shown that.

"I liked the header he scored because he is not tall and you see the way he took the header. He has a determined character and has desire to score.

"He has top quality and is one of player who was with me in pre-season and I knew what he could do.

"But it is good as well. Life gives a chance to young people and hopefully he will make a long career at Arsenal FC. We are proud to give young players a chance.

"I don't know what happened at Chelsea. He has scored goals at youth level and sometimes I don't know why they let him go.

"I don't know why. You see that more and more. Young people travel from one club to another. I don't know."
