Holmes, 20, is back in the media spotlight this week after seeing John Bostock make his Crystal Palace debut as a 15 year-old.
Derby midfielder Holmes also made his first start at the same age and told the Daily Mail: "I've made almost 100 appearances now as a professional. I've been injured for a while - and I'm still only 20. It's different when you are so young, being asked to play, but I looked upon it as a positive."
"I saw a couple of things John did - and he looks to be a good prospect. I didn't understand really the enormity of what I was doing at the time. Perhaps he doesn't. There were no negatives as far as I was concerned, though. As long as he continues to write his own history for the right reasons, I'm sure he'll be fine."
