Nico Rosberg rues disappointing German Grand Prix performance

Nico Rosberg insists he is not struggling with a lack of self-belief despite seeing Lewis Hamilton turn his 43-point championship lead into a 19-point deficit by virtue of the Briton's fourth consecutive victory on Sunday.

Following his triumph at the German Grand Prix, Hamilton has now won six of the last seven races, while taking a clean sweep of all the four grands prix which were staged in July.
