Sergio Perez on Thursday rejected suggestions his form has taken a nosedive because he has already turned his attention to 2013.
From the cockpit of his Sauber last year and in 2012, the 22-year-old Mexican convinced F1 grandee McLaren that he is good enough to replace Lewis Hamilton next season.
McLaren's Martin Whitmarsh, however, has defended his new signing, albeit admitting Perez is "raw" and adding: "If he hasn't something to learn at 22 then there's something wrong."
I am fully focused.
"I am fully focused," he insisted. "What has happened is just a coincidence.
"I just want to give my best, but it's normal people start to make up stories I'm not doing very well following the McLaren deal."
