I get the feeling that if Webber wants to stay on, with the knowledge he is bound to have accumulated at Red Bull, another team will take him on but I can't see it being one of the top 6 teams somehow. I just don't see Red Bull keeping him for another year.
Is he still managed by Briatore? Most of the drives he has got in the past were due to Flavio "placing" him and I think the Red Bull drive was due to Briatore's Renault connections. Perhaps replacing Trulli at Lotus is not too great a leap of imgaination.
