I find it odd that Sergei Ivanov was appointed to referee a match involving two countries (Slovania vs Cyprus) in the same group as Russia. I appreciate that the outcome could not in any way affect Russia's standing in the group, that a very large number of appointments had to be made in this double round of fixtures and that there are still problems with Covid-related travel restrictions, but even so, I would have thought that somebody more obviously neutral could have found somewhere.
Hungarian team out on the same matchday, they could have easily swapped them with no arising travel issues. It's unfair on him to put him in that position, even though it could not affect the outcome there is always someone out there looking for any reason to try and raise an integrity issue or similar rubbish.
