Moyes said: “Ross is a really talented player.
“In Spain, they don't give boys their debuts so young. Maybe we're a bit anxious here – I was hearing a lot about [18-year-old Manchester United striker] Marcus Rashford getting into the England team.
“But I think they're right to just keep them going.
“Ross will play for England many more times, and I think he will develop as well because there's another stage of his career to go when he becomes one of the senior players."
