No, you said "most notable" which is quite different from notable and implies a kind of GOAT status. Don't go back on what you said - your post is still there. I can assure you that in most countries, no one has heard of Wegner. They have heard of the same coaches I mentioned before - Bolls, Lansdorp, Lundgren, Roche, Macci, Braden, Stefanki, Higueras, Gilbert, and maybe Burwash because of his name associated with resorts. People are not so stupid that they will not "hear" about a coach because he is from so-and-so country or that it is possible to keep these things hidden in the Internet age. In the international world of tennis, players will be running to the "most notable coach internationally" in droves. I had asked you before - which upcoming US player is being coached by him? e.g. Harrison is a Bolls product. There is something concrete there, unlike some vague terms.
