Hamilton has work to do to catch Rosberg

World champion Lewis Hamilton says he is "in trouble" for this weekend's British Grand Prix if he does not improve his car.

Nico Rosberg was fastest in both sessions as championship leader Hamilton struggled, particularly in the second session.

Despite his woes Hamilton is full of praise for the British crowd after having not the "easiest" of days at Silverstone.
