Yuki just isn’t rated by Marko and Christian, when was the last time that they talked about promoting him?

I think it is more of an issue that yuki is a Honda backed driver and not a “true” red Bull junior which plays against his promotion chances. He is solid and dependable while not being blazing quick - the exact 2nd driver red Bull are looking for.

Also be is not helped by the fact that horner loves Daniel and is borderline obsessed with getting him back to red Bull.
