Have just watched a young Swiss guy (just 20) called Adrien Bossel come through 2 qualifying matches at Sheffield Futures, beat Konstantinos Kalaitzis (GBR) #1249 and Miles Armstrong (AUS) #718.
He is a left hander and I cant believe he's only got 1 ranking point, really enjoyed seeing him, probably not got enough power to make it at ATP level, but a good player to watch with a nice touch, pulled off a fantastic backhand lob at break point in the penultimate game of the match against Armstrong.
Doesnt answer your question about next Davis Cup star but enjoyed watching him anyway.
All the best!
yeah, I had thought of putting his name in the list but since he almost only played in Switzerland I didn't think he was really planning to become a professional tennis player. I saw him play a couple of times in the swiss interclub where he played sometimes great tennis and sometimes he just crumbled. His game is nice to watch indeed. He can do damage indoors with his serve and forehand. But for now he doesn't really look 20 but more 17-18. If he gets stronger he may become a good player.
Thanks for your post, I'll edit mine and put his name in the list!
