Gartside can already see signs that the "grand plan" is taking shape.
"We have got the best Academy structure we have ever had and kids coming through now who have been with the club since they were seven years old," he told the Bolton News.
"That's unprecedented since the Academy was set up. People mistakenly think Kevin Nolan or Nicky Hunt came through the youth but they didn't. They were 14 or 15 when they came through.
"Joe Riley, Adam Blakeman and Josh Vela - all these lads have been with us for years.
"I have given up trying to work out what the average age of this squad is now because it has dropped so quickly.
"Someone brought it home to me when they said we had a creche for the players' wives and we've run out of kids because the players we have now haven't got kids, and some of them haven't got wives.
"It's the age group and the demographics that have totally changed. It has passed over people, and we haven't really made a big play of it - but it is going to be a real strength in the future."
