Button: Problems masking true pace

Jenson Button says the real pace of his McLaren team has been masked by the reliability problems the British squad has endured during testing. Button had another disappointing session on his final day of testing at Barcelona, the Briton losing valuable time after McLaren decided to replace his engine as a precaution. Button covered 53 laps and finished as 13th quickest out of 14 cars.
