Can't chama be translated to something like "let's go". Seems like Jiri's catchphrase of "Let's go for that" is a very similar vibe to chama. I've noticed that both Alex and Jiri share a lot in their overall characters and fanbases. Both fighters look like they could have been in the Street Fighter video game. Also they have a certain level of authenticity and aggressive fighting styles. I think their careers will be thought of together similar to Shogun and Machida. Made it all the more cool when they showed Jiri getting emotional in the crowd when Alex finished Ank.
Also on a separate thought, I think Jiri's gameplan in the third fight could be to use grappling to tire Alex out in the first two rounds. Once he loses the pop to his punch, he could just blitz attack him in the later rounds and out cardio him to a TKO. It could be similar to Izzy where he needed multiple fights with Alex before figuring out a winning strategy.
