Just seen on the BBC website, the three potential sucessors being lined up by Renault are Senna, Liuzzi and Heidfeld. The fact that they are talking to other drivers I guess pretty much rules Senna out, so will they go with the long term experience of Heidfeld, or the driver who most recently completed a season, Liuzzi?
Personally, I think Heidfeld will get it, he's raced with KERS before I think, he's been around a while and managed to score more points than Kubica in a couple of seasons when they were team mates. I've always liked Heidfeld, but he's never really been able to show why he deserves to be in F1, so I'd like him to take this chance to do so.
Bit ironic if Liuzzi gets booted out of Force India, and then ends up in a more competitive car - and where Sutil was trying to get in to for this season!
