Kobayashi.
Guys its the car not the drivers....look at Webber for example,,,he didnt get all that good overnight....he's got a good enough car and thats making the difference,or Button of last year..couldnt do jack with BAR/Honda and then with a different car he wins the championship.If you replaced Alonso with Vettel dont expect Vettel to start wining all of a sudden.
Hamilton or Vettel. Schumacher would be amazing but I doubt that will happen. Ferrari are very committed to alonso i doubt he'll be let go anytime soon. They really picture him as the next schumacher, and I can understand why. I hate the guy and want to see him fail, but he's an awesome driver. No arguing that.
The two most likely are Vettel and Kubica, I would like to see Hamilton also but he seems pretty devoted to Mclaren but surely he can't stay there his whole career.
Definitely Alonso should stay, he and Ferrari are a perfect match, but if he was to leave for whatever reason I would like to see Vettel with Kobayashi. I do think we will see Vettel in a Ferrari in the future once he grows up a and Alonso retires, Vettel has a looong term contract with RB.
People hold Kobayashi in pretty high regard for accomplishing very little. I don't want to see him in a Ferrari until he proves himself.
Crashing out on the first lap as often as he did at the beginning of the season sounds pretty damn BAD to me.
Since I think Ferrari would be idiots to get rid of Fernando, I would suggest that they get the replacement from a street corner somewhere, preferrably someone with dark glasses, a striped cane, and a cup of pencils for sale. They would pay this person far less than Fernando and could at least show a monetary profilt for their effort.
the guys dials are set to eleven. with all that red mist in his helmet he needs to be in a red car. most of these guys are robots. its fun watching him drive. rossi would be a another choice for me as well. besides trying to understand either one in the post race interviews would be entertaining as well.
