Bielsa could speak decent enough English, there are some funny interviews of him correcting his own interpreter for misunderstanding the question. I think he used it as a convenient shield from the media, he was happy to make interviews awkward. All part of his mystique I guess.See, I don't agree with this. Some people take to learning a new language like a duck to water, some don't. And that's just regular life. Throw in the media trying to twist your every word, find an angle, or get a good story, I don't blame anyone wishing to stick to their native tongue. RDZ's approach is incredibly impressive but it's not for everyone.
