Interesting, Sauber need assurance that Kobayashi can do a valencia every race weekend first.
About renault, Kimi, Heidfeld, Glock, Sato? , all these guys are eyeing that seat. They know it's good.
The funny thing is, there was a joke last year about kimi and him scrambling for a renault seat. The kimi fans scoffed at the thought. Now they would do anything to see him in F1, even if he was driving a HRT.
Renault is now a top team, and with next years regs, they could be championship contenders easily. It's a nice prospect and any one of those 4 guys above could give Bob a run in terms of all out speed; maybe not glock so much, but he's good non the less.
