The highly-rated youngster made the comments after signing a new four-year contract with Forest, as announced on their official website on Tuesday.
“The most important thing is game time,” Walker told Forest’s official website. “I just want to carry on learning, so whatever games I can get I will be happy to play in, making sure I’m improving all the time and implementing what I’m being taught in training.
“It’s a big season for me and I want to hit the ground running when I come back.”
Walker is considered as one of the most promising young strikers in the Championship and broke into the Forest first team in the recently concluded 2014-15 campaign.
In seven appearances in the league for the Reds, the 18-year-old scored one goal, had a pass accuracy of 77% and a shot accuracy of 60%, and won three headers and two dribbles.
The English youngster impressed in those seven matches, and many fans will want him to be given more chances in the first team next season.
Walker is only 18 years of age and has a lot to learn, which means that he will not necessarily be a first-choice striker for Forest at the start of the 2015-16 campaign.
The teenager will probably start the season as part of the Under-21 team, and the number of chances he will get for the senior side will depend on how he performs at the youth level.
