If saldivar goes at lomachenko very aggressively he could definetly pull it off for a UD. Otherwise i would probably favor lomachenko for a pretty comfortable UD.
When and IF Lomachenko defeat a fighter as capable as Sugar Ramos or Ismael Laguana , or at the least win more than 15 fights without a loss to a merely a decent fighter. Let me know. Because he's not on the same level as Saldivar. Not yet anyway. Saldivar would figures out Lomo's movement after a few rds, start timing him, would go on to win a wide dec. The only way Lomo has a chance is if the fight is not a same day weigh in, and he comes into the fight weighing as much as a jr.welter/lightweight
