Vettel not for sale

I'm not sure Dieter can actually say that.  He can try to hold Vettel to his contract, but I expect if he stays up in the points regularly, there will either be a renegotiation or Vettel may start looking elsewhere soon - certainly his phone will be ringing if it isn't already.

Dietrich Mateschitz is delighted with Red Bull's driver line-up, insisting it is among the very best on the Formula One grid.

The team owner's comments follow Mercedes boss Norbert Haug's confession this week that he would like to see Shanghai winner Sebastian Vettel in a McLaren ‘some day’.

Vettel is under contract until next year and Red Bull could have the first option on his services.

"Besides Ferrari, we have with Vettel and Webber absolutely the strongest driver pairing in the field," Mateschitz told the German newspaper Bild.
 
And as for rivals' interest in Vettel, the Austrian billionaire added: "At the moment Sebastian is not for sale."

I think BMW still has a link to Vettel from his early days in F1, not certain it's an option but they have some sort of deal where Seb uses an M5 road car from them. One things for sure though most of the big teams will want to make a pitch for him.

If Red Bull keeps improving, then maybe Dietrich can keep him simply by saying his team is performing better. Whatever the allure of tradition, what an up-and-coming driver like Sebastian needs most is a car that can challenge for the title. Right now, that looks more like Red Bull than Ferrari.
