The midfielder insists he's happy with the way things have developed at Arsenal.
"My progress into the first-team at Arsenal and the senior England squad was quite quick, probably quicker than I ever thought it was going to be," he said.
"I really just try to keep my head down, focused on my targets, and take everything in my stride.
"I have only achieved a tiny percentage of what I want to achieve in a small fraction of my career.
"I know I have got a lot more hard work to do and a long way to go, so I don't really think about how quick things have gone because I just want to keep improving myself and keep pushing on."
