Perez aims for title with McLaren

New McLaren driver Sergio Perez is optimistic he can fight for the drivers' championship in his first season with his new team.

The former Sauber driver says he is not feeling the pressure of driving for the "biggest" team in Formula 1 and is ready to work very hard to achieve his goals.

Perez says he can't wait to get to work and is looking forward to competing with new team-mate Jenson Button.
