Rosberg sealed the world title by finishing second in the final Grand Prix of the season.
Lewis Hamilton could have won the race easily but instead slowed down in an effort to hinder his team-mate and force him into the path of the following drivers to give the Brit a chance of winning the title.
Rosberg managed to hang on and claim the overall win but retired five days after his maiden world championship triumph.
Nico Rosberg and Lewis Hamilton fought three fierce battles for the world title
But the German is still frustrated at the way it all unfolded at the last race in Abu Dhabi.
"It was not right what [Lewis] did," Rosberg said in an interview on In Depth with Graham Bensinger.

It was not the first time the pair had clashed on track in their three consecutive battles for the title as Mercedes team-mates.
The drivers crashed into each other on the first lap of the Spanish Grand Prix, before which Rosberg had won all four of the opening races of the season.
They also clashed in Hungary but now Rosberg has revealed that when he was given team orders in Monaco, he had not hesitated to obey.
"I respected the guidelines, because in Monaco we had exactly a similar situation where I was second, he was third, and I was driving too slow – just as he was in Abu Dhabi," Rosberg added.

"And he got the race win, which helped him in the championship fight as well, ironically.
"And so it was the same situation in Abu Dhabi and he didn’t abide by those rules, so from a team’s perspective for sure that was not the right thing to do but from an individual I can understand why he wanted to try something.”
