It's not unusual for speculation to reach fever pitch when a driver changes employers and has a new team-mate to pit himself against, but it must feel strange to do so as the world champion and yet have a horde of pundits tell you that you're going to get blown away. That was Jenson Button's lot when he arrived at McLaren in 2010. But he settled into his new environment quickly and while Lewis Hamilton did prove to be the faster of the pair, the margin between them was far smaller than many expected - and Jenson demonstrated a cooler head and sharper tactical nous. He must build on that this year.
