German driver Nico Rosberg expects Ferrari to pose a significant threat during the 2016 Formula One season, despite Mercedes producing such a dominant performance last year.
As a result, every minute spent on preparations during the winter break has been optimised and nothing has been taken for granted, from a Mercedes perspective.
"We take the opposition very seriously, especially Ferrari," Rosberg told Sky Sports.
"For sure they are going to be a big threat, so we need to keep pushing. Who knows where are going to be at the first race," added Rosberg.
The rivalry that exists between Rosberg and his teammate Lewis Hamilton has been well documented since the two have started working together. Rosberg insists that did not get in the way of the team's objectives during the pre-season, where every decision taken was in the interests of Mercedes.
"I'm sure there's going to be many more years to go here at Mercedes," said Rosberg.
"I feel comfortable here, I really enjoy being part of the team. We've achieved so much and there is even more to achieve in the future."
"Every year is a big challenge, and every year is a big year. It's a great opportunity at the moment, and I look forward to it. I look forward to this challenge of going up against Lewis again, who's been driving at an extremely high level.
"It's the sort of battle that I relish, that's what I do sports for, it's what I compete for. So that will be good. And let's see how it goes. We're working together."
