Rosberg still 'Practice King' for Mercedes GP

Michael Schumacher was vowing to improve and raise his game after he was beaten to the top spot by his team mate Nico Rosberg in this afternoon's second practice session in Bahrain .

The seven-times world champion admitted to be a little "rusty" over a one lap run, but insisted he would get better. Rosberg's lap times were 0.445 seconds quicker than second-place-man Lewis Hamilton while Schumacher was 0.494 seconds slower than his team mate in third.
