Rasputin it is not news that they have financial problems, Renault don't fund the team anymore, the team was about to leave at the end of 2009, they have Petrov who is effectively (well was) a pay driver, and the main reason he stayed on to this year was because he had huge sponsorship from Russia. But Petrov has proved his worth.
They do have a lot of reserve drivers, I have heard they (Renault) have invested a lot in Romain Grosjean, I think he is quite a good talent and was given an unfair crack, but with so many drivers, they will have to pay them will they not? I Renault are in a bit of problem here driver wise, the way Ferrari where back in 2009.
Main thing is, Heidfeld needs to prove to be the team leader that the team is looking for, so far I have to say he isn't doing the job.
