"We went to referee at an under-19s tournament, where you are compared with your peers. Unfortunately I didn't make it last year," he said.
"We went to a training camp a couple of weeks ago, where I was promoted to the development squad. I was told one of the refs was let go as he didn't meet his obligations. There was a bit of luck involved."
