There is always talk about linking any driver who wins a race or two to Ferrari. Last year and the year before, all the talk was about Hamilton being pursued by Ferrari. How Ferrari had contacted him, and how he just "looked" like a Ferrari driver. A year or so later, after Vettel`s victory at Monza, the websites started reporting how Ferrari wanted him in their car and during all this time, Alonso has constantly been linked to a future Ferrari move and there were once some reports of Kubica going there. So take all that stuff with a pinch of salt.
There is no denying Vettel's undoubted talent. The kid is for real, but I am surprised how much is made of his win given that his team-mate finished very close to him, and had it not been for that one moment in the race for Webber, he would have been even closer. That says a lot about how good the car was in the wet and also a small mention of how the two Red Bull cars blew away the Brawn GP, who clearly are the class of the field at the moment. So, it's not like Vettel ran away to victory up at the front of the field and his team mate languished somewhere at the bottom of the top ten.
As for who goes to Ferrari, i think a lot depends on what Ferrari do this year and the following year. Alonso will not agree if it's this Ferrari, unless he has one more world title. He can then go, set up camp and start the rebuilding process which might take a couple of years and then be there to reap the rewards. If his Renault continues to be better than the Ferrari, and most likley it will be, he is not likely to join them anytime soon. One thing is certain though, if he joins Ferrari, there will be no place for Vettel or anyone else. Ferrari will revert back to having a clear number one and have a side kick for Alonso. That is the way to win as was amply shown by Schumacher over the years, it's the way Hamilton won, BMW clearly have a clear number one and team leader and that is what Ferrari expected from Raikkonen. They will get it from Alonso or Vettel, who ever gets there first. Smart money is on Alonso:D
