It was the biggest talking point at the end of the Formula One 2016 season.
Mercedes driver Nico Rosberg had held off a strong challenge from his rival and teammate Lewis Hamilton to lift the first Drivers' Championship in his Formula 1 racing career.
To the surprise and shock of the world, Rosberg quickly announced his decision that he would be retiring from the sport, leaving a massive seat to fill at the reigning Constructors' Champions Mercedes.
After much speculation and many rumours, following on from a season of strong performances at Williams, it was Finnish driver Valtteri Bottas who was chosen to replace the then World Champion Rosberg.
Quickly the chat changed to how would he interact with Hamilton, who had a much publicised and difficult relationship with Rosberg within the Mercedes garage.
Bottas has had his say on this subject in particular in an interview with Monster Energy.
After being asked about how the two men get along, Bottas said: "I think it’s because we both understand the facts that we do want be better than each other on the track. Definitely.
"When he’s better than me on track, for sure it doesn’t feel good for me. And vice-versa.
"We know the facts and still when the situation is not ideal, we know we need to work as a team and we have no reason to hide anything from each other. We want to beat each other fair and we give respect.
"It was actually in Melbourne when we agreed before the race that we agreed upon these things to where we were both on the same page. We just want to go out and race and work as a team and get the job done."
Undoubtedly there would have been some fear from Bottas when replacing Rosberg, as he would have been all too aware of the bad blood between the former teammates before he got there.
Going by what he has said, Hamilton and Bottas seem to have been able to carve out a respectful relationship, whilst also maintaining the competitive edge needed to be a successful team.
Whilst undoubtedly Hamilton was the star of this season, the contributions Bottas made to Mercedes winning the Constructors' title again cannot be overlooked.
Mercedes themselves will be delighted that everyone associated with the team have carried on their winning ways, and have brought team harmony along with it by appointing Bottas.
