I heard it, its a brazilian guy. Its perfect. This guy is from Rio de Janeiro, where the "s" has a similiar sound as the "s" in Portugal. But, seriously, do you consider that a "SH" ? I dont think so. For me "sh" is a really different sound. Like aSHley, caSH, caSHley cole. In the video and in the site you posted, the pronounce is the same, its because in portuguese when you talk fast, the "s" is not as strong as saying it slowly. Specially big names like Andre Villas-Boas, in general you speak it faster than shorter names. I dont find that to be and "sh". As I said, in Daily Mail there was a video when the guy tried the Vilash Boash and it sounded awful. I think the "ss" sound is more appropriate to describe that sound than "sh". Class - Cash. The ss is more similar to the the sound in the video I posted and in the pronounce of the brazilian guy. But is difficult to discuss this, because you are from Greece, I dont know how you pronounce cash or Ashley.
