However, Marko has playfully suggested that Vettel's switch could be a bad choice.
He told F1's official website: "Ferrari is still the name in F1. It's a myth, so every driver yearns to go there in their racing career. Sure, much of it is about illusions.
"Sebastian has already won [the title] four times. Now it's time for the myth. I also believe that the moment to move was ideal: Ferrari is down, and in such a situation you can dictate your conditions."
Alonso's future on the F1 grid is far from certain, with the possibility that the two-time drivers' champion could be left without a race seat for 2015, despite continued links with a switch to McLaren.
