roids or not, he's a tough guy and there are a lot of interesting match ups for him in the division. Despite his loss to Wlad, and him testing positive for banned substances he's probably pretty big in Poland now. within a year or Artur Szpilka would have beaten a few decent Journeymen and Wach could be his first big fight. I'm sure that fight would be very popular in Poland and would garner a fair about of attention in general. I would also like to see Wach/Helenius, that would be a good fight.
imo wach is not that easy to beat. you can't knock him out but you can outpoint him if you are aggressive and you have a high workrate. i the wach from wlad's fight would stop fury, price, adamek, wilder and beat helenius, arreola and chisora. guys like jennings, haye and pulev would beat him by ud
