Definitely not, but Alfa Romeo are a title sponsor so in a way they're almost a Ferrari B-team. I imagine they get a lot of value from associating him with their brand.
there HQ is down the road from where he lives - so suits him, and they get an experienced drive to push the car forward, and if required in 2019 follow ferrari-B-team orders like good boys.....
Gotcha. But a contender they surely ain't?
Well, I guess Räikkönen just wants to drive and compete.
