Lewis Hamilton: My relationship with Nico is 'sweet'

His sometimes volatile working relationship with Mercedes teammate Nico Rosberg continues to make headlines -- but Formula One world champion Lewis Hamilton insists that everything is "sweet" between the pair. Hamilton, whose team boss Toto Wolff had warned that one of the two drivers could go if relations did not improve, said "only positives" lay ahead "for Mercedes and us." Speaking earlier this month, Wolff said: "The guy in the other car cannot be your friend. "But we need to be careful that it doesn't spill over on both sides of the garage. We have seen at teams in the past that there is a competition that has been created that is not good for the dynamics within the team, and this is what I try to re-emphasize. I will have a close look at it."
