Rubens was on twitter saying he’s waiting for good news from Williams so he’s defiantly hopeful about his spot, which if Senna was running for it, he wouldn’t be so hopeful. It’s a huge dilemma for everyone really, Senna is a quick-ish driver (all be it, hyped up a lot because of his surname) but he also has sponsorship. It would be good to see him just race one full season for crying out loud. It’s hard to judge him after half, probably less, a season driving a wagon (HRT) and then half a season in a cart (Renault). All we know is that any driver that is out of contract now is looking at that one seat because it’s the best chance they have. So Algersuarui, Buemi, Senna, Barichello, Liuzzi possibly, Chandhok, Nick Heidfeld, D’ambrosio, Mansell, Prost could be linked to a race drive at Williams, just because they have a seat going spare.
