Just noticed @jensonbutton unfollowed, thats a shame. After 3 years as teammates, I thought we respected one another but clearly he doesn't.
Funny thing is, we are STILL teammates! All good tho, I plan on giving this team & fans all I got til I cross the finish line in brazil!!!
My bad, just found out Jenson never followed me. Don't blame him! Need to be on Twitter more!

I was brought up on the great stories of Ayrton Senna's many world championship triumphs for McLaren, and I'm truly honoured they've chosen me to partner Jenson (Button) from 2013 onwards.
I've spent the 2012 season working very hard to demonstrate my potential, but I've always remained humble and focused.
While I'm still fully focused on doing my best for Sauber for the remainder of this season, I'm already massively looking forward to working with everyone at McLaren.
