The 21-year-old said: "It's amazing how things have worked out.
"I'm back with my home-town club and it feels fantastic.
"It's a dream come true for me to have the opportunity to join my local club and such a big club as well.
"There were other teams showing an interest in me, teams from the Championship.
"But once I became aware of Forest's interest, there was no question of me going anywhere but The City Ground."
