Nico Rosberg will not be cowed by having a double world champion as team-mate next season, according to Mercedes' Niki Lauda.

Speaking in the wake of the German's disappointing end to the season, where his championship bid ended with ERS failure and the ignominy of being lapped by team-mate and title rival Lewis Hamilton, Lauda insisted that the setback will only act as a spur for Rosberg to raise his game in 2015.

"[Hamilton's title] is exactly what we need, because Nico will fight back," the three-time champion claimed when asked how the team dynamic would be altered by the Briton's success, "There is upwards potential, something still to come from his speed and performance, and the technical inputs he gives, so next year is going to be fun again between the two. I hope nobody else will interfere..."

After the enmity the existed between the two drivers mid-season, Lauda believes that there will be no problems next year, with Rosberg's post-race congratulation of Hamilton underlining the positive side of their relationship.

"The outcome today is unbelievable, fighting each other, then hugging each other and one congratulating the other one," he noted, "When you overcome all these issues, when one won the championship and the other didn't, one hit the other and the other didn't, it's got to be easier next year because they respect each other on their level of performance."
