Button admits Hamilton has been faster in 2010

McLaren newcomer and reigning world champion Jenson Button has admitted that he has not been as fast as his teammate Lewis Hamilton in 2010.

The 30-year-old, who has won two grands prix compared with Hamilton's three so far this season, said his countryman has been better at the wheel of an unbalanced car, and over a single qualifying lap.

"I need a car that is more stable than he does. In that respect Lewis is very strong," Button said in an interview with The Independent.
