Toto Wolff: 'Nico Rosberg suffered understeer problems in qualifying'

Mercedes team boss Toto Wolff has revealed that Nico Rosberg was left frustrated with balance issues during qualifying for the Hungarian Grand Prix.

The German will start second for tomorrow's race behind his teammate Lewis Hamilton, and Wolff admitted that Rosberg struggled throughout the session.

He told BBC Sport: "It was a very good lap indeed from Lewis Hamilton. Nico Rosberg wasn't really happy. The car felt terribly wrong the the beginning. The understeer was coming back and going."

Hamilton has beaten Rosberg in nine out of 10 qualifying sessions this season.
