well he did work on his grappling after his last fight in one fc, this guy is good, the afghans on youtube are so racist towards us paki's like seriously, waqar umar, is the only paki to ever beat an afghan, i hope he has great success, he will be a top fighter one day, because he had a realization about his career that he shouldn't have focused on his striking and should've focused a little more on his grappling, and i think he trained grappling in another country or something because you can't learn the grappling that he had in pakistan.
edit: i forgot to mention that i don't think that umar will 100% win, but if he does i'll be proud to call myself a pakistani. although pakistani's mostly have more success in muay thai than mma, they are starting to make a comeback in mma.
