He had been on Watford's books since the age of 10, but when it came to the club offering full-time YTS places, Young was turned down on the grounds that he was considered physically too slight.
He told the Sunday Times: "I was told I could sign as a part-timer which meant I went to school in Stevenage and trained at Watford three times a week. I just thought to myself that I was going to put my head down and prove wrong the people who were in charge at the time. Everybody has to make decisions in life and luckily for me I've turned it around and I am where I am today."
It helped that he was eventually joined at the club by his two younger brothers, Lewis and Kyle, who are still coming through the youth system at the club.
"It was always a dream we would play with each other or even against each other. Watford is a club that produces youngsters. You only have to look at the number of youngsters who they've brought through and have gone on for bigger things. So the club has done really well for players like myself."
