Indeed, Pearce suffered an ill-fated spell at the City Ground, with the club's owner being forced to dismiss the Forest legend with a heavy heart.
However, the 53-year-old left a lasting impression with young forward Walker, who admits it was Pearce who was the inspiring presence for him at Forest.
While he played for the first team later on in the season, the 18-year-old forward says, it was Pearce's decision to take him away with the senior side on pre-season that really got Walker's confidence up and allowed him to develop into a player capable of chipping in for Nottingham Forest.
He said: "It all started, really, when Stuart asked me to go away with him in pre-season. That helped me a lot, getting to know the first-team players and getting more confident around everyone.
"That really brought on my football throughout the season, even though I didn't play much first-team football at first."
Under current coach Dougie Freedman, of course, Walker is likely to get ample opportunity to take his game forward even further, as the Nottingham Forest boss is known for his policy of giving youth a chance.
What will the upcoming Championship campaign hold in store for the 18-year-old?
