Bored and perusing the youtube...
There's not a lot of footage of him (in English, at least). This is from 2017, three years ago, but shows the talents already there.

This clip of Denisenko is good, but you can skip the first :45 of his celebratory high five-byes at the bench. The soundtrack is horrible too, lol, but still worth watching, even if on mute.

Can't wait to see Denisenko play, I heard good things about him after the last World Jrs tourney. Some said he was one of the best players there.
The best clip I found may be this interview from Panthers 2018 rookie development camp

The highlight being the "interpreter" who is wearing the Panthers shirt saying, "my English not so good". He then proceeds to show that he wasn't really kidding around. You won't get much more than a laugh out of it. You can't hear any of the questions being asked, which would help.
LoL, who knows what the questions actually asked might have morphed into through this guy's translation to Denisenko.
Cheers!
