I doubt he has one and he wasn‘t the one who announced they would interview Eulalio, that was just an accident as well. But on the 2nd stage, after figuring out it was Silva he called him Giulium Giuliomero Thomas Silva, which are some terrible mispronunciations of Guillermo. But I doubt it‘s something personal, nobody‘s told Bengsch that the Ecuadorian rider isn‘t called Narvarez for years either. Migels has also somehow confused Ghebreigzabhier (or Ghebreizgabhier as he calls him although that may be correct, I‘m not an Eritrean pronunciation expert) with Sobrero multiple times this Giro in situations where Ghebreigzabhier had already worked hard and been dropped. I think he just likes to say his name.
