The trouble with Nico Rosberg is that his talents are seldom appreciated as a standalone driver.Son of 1982 world champion Keke, the German shot into the limelight when he joined Mercedes as a teammate to seven-time world champion Michael Schumacher.Rosberg impressed by beating the legendary champion in each of the three seasons they were paired together, but hardly got any credit for it. It was argued that Schumacher was woefully inadequate.But 2013 cemented his place as a competitive driver. Although beaten by teammate Lewis Hamilton in the standings, Rosberg’s two wins against the Brit’s solitary victory, coupled with a few reliability issues, suggested that the German was on par with champions in terms of his performance.He may be the son of former champion, but this German wouldn't want to give up his racing gloves without making a name for himself in Formula One.Rosberg burst into the scene with a points-on-debut performance in 2006 with Williams but has been plagued with underpar cars to the frontrunners throughout his career.But it convinced Mercedes to sign him up in 2010. Unfazed by the seven-time world champion’s record, Rosberg came of age racing in the three seasons with the veteran.However, his strong results in an uncompetitive car were overshadowed by Schumacher’s inability to get the team going. It was even more unfair particularly when he was the one who gave the brand new Silver Arrows its first win at the 2012 Chinese Grand Prix.Now teamed up with old buddy Hamilton – the pair raced each other during their karting days – Rosberg is now the established driver in the team. And if he was not hindered by a seven-time world champion, Hamilton's sole title would make things a lot easier for Rosberg.
