In Sweden we have a quite famous sports commentator (ice hockey/ football) that regularaly plays tournaments. I met him two weeks ago and it was quite an experience. He was kind of commentating the game as we were playing it. It was so hard not to laugh. I completely lost my focus.
I know very interesting vlog on YouTube of Russian professional TT coach.
His students are in the national team for mini-cadets and cadets.
A lot of "player tributes", "professional trainings", professional match analysis.
