Nico Rosberg admits he cannot feel ecstatic about winning races when team-mate and title rival Lewis Hamilton has been handicapped by unreliability.After securing his seventh consecutive win with a straightforward victory in Russia, Rosberg has opened up a 43-point lead at the top of the world championship. But while Rosberg has enjoyed a trouble-free start to the new campaign, reigning champion Hamilton, who has previously beaten Rosberg in every season of their three-year partnership, has been waylaid by two engine failures and three separate first-corner collisions.With the critics claiming that Rosbergs title lead will lack credibility unless the German prospers in a head-to-head fight with Hamilton, even Rosberg himself admitted that his joy at opening up such a large lead in the title race has been diluted. I cant say l miss it [fighting with Hamilton] because it is awesome to win races and in the end it doesnt matter how, Rosberg told Sky Sports F1. Winning is great and what Im here for. But the ecstatic feeling isnt there, its there when l win a battle with Lewis, thats what gives the ultimate thrill.Russian Grand Prix driver ratingsExcept for beating Hamilton off the line in Bahrain, Rosberg is yet to make a single overtaking move on track this season. While his victory in Sochi represented his first F1 grand slam - pole position, fastest lap, and victory after leading every lap - Rosberg acknowledged that it was bereft of the special ingredient that only a wheel-to-wheel contest with Hamilton could provide.A straight fight with Lewis is what l am here for because hes the benchmark and I look forward to it when it comes, he added. Its always going to be a tough battle against him because hes as motivated and as quick as ever. Toto Wolff has strongly denied claims from some fans that the team are sabotaging Lewis Hamiltons season Hamilton, meanwhile, has defended his Mercedes team but admitted he doesnt understand why the world champions swapped personnel from one side of their garage to the other during the winter in an apparent bid to improve team harmony.From my side of the garage the mechanics are having a hard time, Hamilton told Sky Sports F1. But I have absolutely every bit of confidence and faith in them.The majority were on Nicos car last year and Nicos guys were with me for the last three years since I joined. The team all of a sudden swapped for no apparent reason.Toto Wolff Q&A Every race live in 2016 Sky Sports F1 brings you every race live in 2016.
