Arsenal boss Arsene Wenger admits Alex Oxlade-Chamberlain's development has surprised him.

Wenger has backed the 19-year-old winger to shine for England.

Wenger, so often opposed to his stars going on international duty, said: "He is ahead of schedule, yes.

"It could be bad if he was big-headed. But he is very level-headed, very humble. So I think it's good for him."
