I agree one of the Euros would be good.
Turpin was involved in a few different VAR decisions which is perhaps why he's appeared quite a bit. In general, VAR seems to have been quite well handled in the CL - probably helped by most of the officials being the very best around - so there perhaps isn't always too much to focus on. (I know handball gets a lot of focus but that's more a difference in our interpretation I think.)
I'd like to see more of the travel beforehand, pre-match meetings and instructions, more detail in the interactions between referee and VAR, and post match debriefing and analysis by UEFA committee after. You could probably spend 20 minutes on one match easily instead of 2 minutes of the referee saying how much he likes the job and having a highlights package of the goals.
