Toto Wolff has moved to damped speculation that Mercedes may look to reassess their driver line-up by describing the Lewis Hamilton and Nico Rosberg pairing as "ideal".
Mercedes dominated the 2015 season although the harmony in the team was often punctuated by high-profile spats between the drivers.
However, Wolff has offered his backing to the pair, insisting that their differences helps makes Mercedes as strong a team as possible.
“If we had two Hamiltons, the team would have probably exploded," said Wolff. "But two Nicos wouldn't make it easier either.
"The combination of the two is quite good. It is the ideal situation, even if it makes life hard for us sometimes. But precisely because they are so different, with individual approaches, it helps us to be better.”
Hamilton claimed the world title at the US Grand Prix in October, but then had to watch Rosberg win the remaining three races of the season.
Wolff, though, does not believe the noticeable drop in Hamilton’s performance is anything to worry about.
"Lewis had achieved his goal, bagged the title and then relaxed a bit. Although perhaps only subconsciously,” he added.
“At the same time I don't want to detract from Nico's performance, which was great.
"It shows we have two drivers who will be driving at peak performance for us next year, which is the key to success even though it caused us a few grey hairs."
