The 24-year-old midfielder is one of the best players in the Forest squad, but his overall form this season has not been great.
The former Arsenal man has scored nine goals and created 56 chances in 27 Championship appearances so far this season, while having a pass accuracy of 75% and a shot accuracy of just 40%.
Lansbury struggled to score goals under then-manager Stuart Pearce, but he has five goals in five games since Freedman took charge of the Reds last month.
The midfielder’s form has been crucial in Forest pushing up the Championship table, and Freedman has now highlighted the reason behind his good performances of late.
"I don't know what happened previously before I got here with Henri," the Scot told BBC Sport.
"All I can say is that without the fundamentals that we work on it wouldn't let the Henri Lansburys and Dexter Blackstocks and Chris Burkes flourish.
"We base ourselves on hard work, on team spirit and team desire and then that will let talent flourish.
"He's doing very well, but I do believe it's been a whole round group that's helping our talent to come to the top."
Lansbury is a very talented player and is arguably good enough to play in the Premier League, and it is indeed great for the Forest fans that he is back on form.
The midfielder seems to be enjoying his role under Freedman, and he will be hugely important in Forest’s promotion push next season.
