As for Horner, that's just what I think. But Ferrari did give him an offer a couple of years back after they gave Binotto the sack. Pretty sure they're interested in Horner.
And I don't think Newey is taking any job after this season. I think he'll take a year off.
Toto Wolff wants Verstappen so bad. He is ready to express his admiration to Verstappen at every opportunity. It wouldn't be bad to see him driving for Mercedes. Russell and Verstappen in the same team. Sounds interesting. Their engine for 2026 season is said to be competitive. But we don't know much about how strong the car would be in general.
I have heard Vasseur blocked the way for Newey to join Ferrari. If it is true then I would rather see Horner as the new boss. Last, I feel like Newey will sign for a team rather than taking a year off. But we will see.
