The 18-year-old forward scored his first goal for Forest on Monday, as the Reds played out a 2-2 draw with Brentford at Griffin Park.
The youngster, who had came on as a substitute in the 41st minute, found the target just past the hour mark when he smashed the ball past David Button after some neat footwork following Karl Darlow's long punt forward.
Freedman took off Walker in the 75th minute, but he was impressed with what he saw of the teenager, highlighting both the positives and the area he needs to improve on in his game.
“He’s an exciting prospect,” Freedman told BBC Nottingham Sport. “The biggest advantage he’s got is that he’s a very well-grounded, level-headed boy that turns up every day and works hard.
“How good can he be? I believe he can play for the football club for a long time, and I believe that he can make the striker role his own in the very near future.”
Area to improve on:
“He has got huge potential, and it is a credit to the academy,” said the Scot. “They are obviously doing something right at the football club.
"All I am going to do is polish them up on the final touches. Maybe Tyler in the first half with the chance he was a little bit too excited, certain things like that…
“I am very pleased to say that he is a wonderful young asset for the football club who is only going to get better."
It seems that Freedman rates Walker highly but still sees areas to improve on, which makes sense.
Walker is just 18 years of age and broke into the first team only last month. With time, the youngster will certainly improve and develop his game.
