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."

Nico Rosberg unsure how he beat Lewis Hamilton in late 2015 run

Nico Rosberg says he does not know how he managed to turn the tables on Mercedes team-mate Lewis Hamilton and end the season with a run of success. Hamilton won the title with three races to go, all of which Rosberg then won. Rosberg said: "Qualifying, he did a better job - up to the point he won the title it was 12-three or something. "That was my strength last year. Strange it turned around. Tough to understand it. I don't know exactly why; I just need to keep it going." Hamilton won the title in 2014 despite qualifying behind his team-mate more often than not, passing Rosberg on track a number of times to take 11 wins to the German's five.
