Maybe a little bit premature!....The only uncertain thing is the Renault power unit...if Redbull cannot get the Honda working or find another engine that can compete with Mercedes or Ferrari.....then he will be off!....do not rule out him moving to Mercedes whilst Bottas moves back to Williams.....As with drivers and cars...performance decides value.....if the Redbull performs as it did this weekend then he has no reason to move....the power unit is Redbull`s major concern as Renault will terminate the contact at the end of the 2018 season...but even if he did move to Ferrari...they are still coming second!....and in F1 there is only one winner.
