The attacking midfielder has been named January's Football League Young Player of the month.
He follows in the footsteps of Dele Alli, Wilfried Zaha and Victor Moses in winning this award and will be hoping to carry on his good form in the weeks and months to come in a Forest shirt.
"I have never won anything like this before.
"It was a bit of a shock. I have seen some of the players who have won it and there are some great players.
"It's good recognition for the way I have been playing.
"I had a tough start this season with injuries and the illness but it is good to get back in the team and get a run of games. I have progressed and definitely got better, both physically and technically.
"I have been consistent and have added a couple of assists and a goal to go with that."
Osborn did struggle to find his form in the early stages of this season but he is now clearly in a good place at the club - thriving in a first-team role handed to him by Dougie Freedman.
The 21-year-old has recently been a big feature in Forest's good unbeaten run in the Championship, which came crashing down at home to Huddersfield Town at the weekend.
He will now be hoping to continue his fine form and get Forest back in contention for the play-off places as soon as possible.
