Esteban Gutierrez made a surprising admission at last year's Brazilian Grand Prix when he faced the press for the first time since being confirmed as a Sauber driver.
Far from the usual bluster of someone stepping up to Formula 1, he declared frankly that "it doesn't make sense to say I am 100 per cent ready; it is difficult to say or judge right now how ready I am."
Inevitably, this grabbed the headlines. But while the Mexican later back-pedalled, what he said was entirely correct. There's no shame in it, for the combination of the testing limits and the complexity of a 21st-century grand prix car makes it incredibly difficult for any rookie legitimately to describe himself as ready.
