Rosberg admits Hamilton issues

Nico Rosberg appreciates his Mercedes bosses have endured a "very difficult" time handling his relationship with Lewis Hamilton this season.

Motorsport boss Toto Wolff, non-executive chairman Niki Lauda and executive technical director Paddy Lowe have been forced to contend with a fair share of issues between Rosberg and Hamilton.

The partnership threatened to explode at one point over the course of the Monaco Grand Prix weekend in late May when Rosberg took pole via a dubious manoeuvre during qualifying that Hamilton believed was deliberate.
