Nico Rosberg finished in second place behind teammate Lewis Hamilton at the Abu Dhabi Grand Prix to secure his first driver's world championship, but admitted he felt stress and pressure during the race.
Rosberg's race was made more difficult due to his teammate's deliberately negative tactics; Hamilton drove slower in front in order to allow Sebastian Vettel and Max Verstappen gain ground on the German.
However, the 31-year-old held on to prevail and admitted he his anxiety in the driver's press conference: "The feelings out there in that battle with Max, unreal" Rosberg exclaimed whilst shaking his head.
He continued: "I hope I don't experience that any time soon again...and then the same again there at the end, pressure on from behind and Lewis driving slow in front...that was a tough one"
His displeasure with Hamilton's tactics was palpable and the newly crowned world champion made no effort to hide it.
Rosberg was then asked about his state of mind and replied regarding today's race: "It was so intense the race, it's going to take some time to settle in and come out because it was really intense out there and so tough.
"In the end, those last couple of laps with those two guys behind, you know if I dropped behind them it's over so it was not enjoyable"
The relief was written all over the German's face but he soon lightened up and embraced his family before conducting a cheerier interview in which he expressed his joy and excitement about the upcoming celebrations.
Rosberg added: "It feels unreal, I can't wait to share that with all my friends...a lot of my best friends came so it's going to be an awesome night".
Rosberg becomes the 33rd driver to win the world championship with his triumph in 2016 and joins his father as a world champion.
They are just the second father-son duo, after Damon and Graham Hill, to both win titles in the sport.
