I saw his two matches live and it looked quite okay, at least some potential was visible. An indoors player
I saw him this week in Freudenstadt. Great service and a very hard-hitting guy who plays "Boom-Boom-Tennis". Interesting to watch.
Nevertheless, he doesn´t move very fast and he always plays the same with no surprising shots. For this reason he has lost most of his matches against opponents who have a higher ranking.
He has potential for the Top 100, no doubt, but I cannot believe that he can be a Top 50 player.
