Here. The headline is "I am not afraid of Magnus!", but that doesn't even rise to the level of "dog bites man". Even if the mere thought of Magnus Carlsen caused him to break into a cold sweat, he's not going to say that he's intimidated in any way. Moreover, while the headline makes it sound as if Karjakin was making a bold proclamation, laying down the psychological gauntlet, the fact is that he said it only after about 27 questions about Carlsen culminating in an assertion from someone else (Daniil Dubov) that he - Karjakin - wasn't afraid of Carlsen. Karjakin simply agreed, without an exclamation point.
Instead, the really juicy bit, though it's only a possibility and not a settled fact, is that Vladimir Kramnik might end on Karjakin's team. If it happens, that would be a huge boon for Karjakin. Kramnik is on the short list of the world's best-prepared players, and his experience would be invaluable to Karjakin as well. The battles between Kramnik and Carlsen over the years have been good ones, so while a match between the two would have been best a proxy war of sorts wouldn't be a bad substitute. It hasn't happened yet, though, and I suspect that even if it does we won't hear about it until after match, and even then maybe not unless Karjakin wins it.
