Lewis Hamilton admitted he has to do a better job to get back on Mercedes teammate Nico Rosberg's pace after a poor Abu Dhabi Grand Prix.
Although Hamilton qualified on the same row as Rosberg in fourth place, but while the German held position in the race and claimed a podium finish, Hamilton fell back to seventh. A poor start and getting stuck behind slower cars on different strategies contributed to his slump.
"Clearly with Nico's result the car's better than what I'm able to bring home with it," said Hamilton. "Same old... different day. It's the same every race. It can't be other people's fault.
"Nico's been getting great points for the team. I just need to work harder to try to do the same."
Hamilton had a last-minute scare on the grid when a rear brake problem had to be fixed.
"The guys did an incredible job to put the car together," he said. "I just want everyone back home to know I'll keep pushing."
